Question 2.
Distinguish between botanical gardens, zoological parks and biodiversity parks with reference to characteristics.
Answer:

3. Answer the following questions

Question (A)
Jijamata Udyan, the famous zoo in Mumbai has acclimatised Humboldt penguins. Why should penguins be acclimatised when kept at a place away from their natural habitat?
Answer:

1. Zoological park (zoo) is a type of ex-situ conservation in which wild animals are kept in captivity.
2. Humboldt penguins are native to South America and the surrounding environment differs significantly at Jijamata Udyan (zoo) in Mumbai.
3. In order to ensure that these penguins survive longer and are healthy they need to be acclimatised (adjust) to their new environment slowly.
4. If they are not acclimatised or the facilities in the zoo where the penguins are kept are not optimal/ suitable, they may develop abnormal stress and exhibit unusual behaviours due to it.
5. These penguins may also be more prone to contracting certain diseases, since they are suited to living in a particular climatic condition.
6. The enclosure of these penguins consists of water pool, air handling units and a chiller system to maintain temperatures between 12 – 14°C, where the penguins were kept for around 8 to 10 days to get acclimatised to their new environment before allowing any visitors inside the zoo.

Hence, Humboldt penguins need to be acclimatised to their new surroundings, when kept at a place away from their natural habitat.

Question (B)
Riya found a peculiar plant on her visit to Himachal Pradesh. What are the ways she can show it to her biology teacher and get information about it?
Answer:

1. Riya can press and mount the plant specimen on a herbarium sheet and preserve the dried plant material, until she returns back from her visit.
2. She can also write any available information regarding the collected specimen on the herbarium sheet, which can be useful for further studies with her biology teacher.
3. Various taxonomical aids can be useful to get information about this peculiar plant.

[Note: In order to conserve the local flora, Riya can collect photographs ofplant and describe it’s structure to her teacher.]

Question (c)
At Andaman, authorities do not allow tourists to collect shells from beaches. Why must it be so?
Answer:

1. Seashells are an important part of the coastal ecosystem and are crucial for the survival of various marine creatures.
2. They provide material for building nests of birds and also act as a substratum for attachment of algae, sea grass, sponges and various microbes.
3. Fishes use shells for hiding from predators, whereas hermit crabs use shells as temporary shelters.
4. Removal of seashells from seashores may also indirectly affect the rate of shoreline erosion.

Hence, in an attempt to protect the ecosystem, authorities in Andaman do not allow tourists to collect shells from beaches.

Question (D)
Why do we have greenhouse in botanical gardens?
Answer:

1. Greenhouse is a structure with suitable walls and a roof in which plants are grown under regulated climatic conditions.
2. Most botanical gardens exhibit ornamental plants which require stringent/ optimum climatic conditions for their growth and/or flowering.
3. The greenhouse associated with botanical gardens are also used to grow and propagate those plants that may not survive seasonal changes.

Question (E)
What do you understand from terms like in situ and ex situ conservation?
Answer:
1. In situ conservation: It includes conservation of species in their natural habitats. Grazing, cultivation and collection of products from the forests is banned in such areas. Legally protected areas include national parks, wildlife sanctuaries and biosphere reserves.
2. Ex situ conservation: It includes conservation of species outside their natural habitats. Species are conserved in botanical gardens, culture collections and zoological parks.

4. Write short notes

Question (A)
Write a short note on role of human being in biodiversity conservation.
Answer:

1. Due to rapid increase in human population and industrialization, humans have over-utilized natural resources; leading to degradation of the environment and hence only humans can help conserve the ecosystem.
2. Humans are capable of conserving and improving the quality of nature and thus, can play a major role in biodiversity conservation.
3. In order to conserve biodiversity and its environmental resources, humans must use the resources rationally and avoid excessive degradation of environment.
4. Human beings are stakeholders of the environment and need to come together to overcome pollution and improve the environment quality in order to conserve biodiversity. E.g. Ban or limit on use of harmful products (plastic, chemicals, etc.) that are toxic to various birds, animals, etc.
5. Human beings also play a role in conservation of biodiversity by establishment of various sites for in situ (national parks, wildlife sanctuaries and biosphere reserves) and ex situ (botanical gardens, culture collections and zoological parks) conservation.

Question (B)
Importance of botanical garden
Answer:
The importance of botanical gardens is as follows:

1. It is a place where there is an assemblage of living plants maintained for botanical teaching and research purpose.
2. Botanical gardens are important for their records of local flora.
3. Botanical gardens provide facilities for the collection of living plant materials for botanical studies.
4. Botanical gardens also supply seeds and material for botanical investigations.
5. The development of botanical gardens in any country is associated with its history of civilization, culture, heritage, science, art, literature and various other social and religious expressions.
6. Botanical gardens besides possessing an outdoor garden may contain herbaria, research laboratory, greenhouses and library.
7. Botanical gardens are not only important for botanical studies, but also to develop tourism in the country.

Question 5.
How can you, as an individual, prevent the loss of biodiversity?
Answer:
As individuals, we can prevent loss of biodiversity in the following ways:

1. Increasing awareness about environmental issues. Making posters that provide more information about biodiversity conservation, to raise public awareness.
2. Increased support and/ or active participation in government policies and actions laid down for conservation of biodiversity.
3. Protect various plant and animal species in our surrounding.
4. Set up bird and bat houses wherever possible.
5. Prevent felling of trees especially native plants or trees in a particular area.
6. Reduce, recycle and reuse resources. Especially, reduce pollution and use of plastic bags and other materials that are potential threats for the environment.
7. Use environment friendly products, segregate and dispose garbage correctly.
8. Convince people about the importance of trees and the need to participate in tree plantation campaign.
9. Obey the rules that fall under Biodiversity Act.

[Students are expected to perform the given activity by themselves under the guidance of their teacher.]

Question 2.
Find out information about any one sacred grove (Devrai) in Maharashtra.
Answer:
Sacred groves in Maharashtra are located in districts like Ahmednagar, Bhandara, Chandrapur, Jalgaon, Kolhapur, Nashik, Pune, Raigad, Ratnagiri, Sangli, Satara, Sindhudurg, Thane, Yavatmal.
[Source: Data as per C.P.R. Environment Education Centre, Chennai.]
e. g. Sacred grove of Parinche valley, Pune district of Maharashtra:

The Parinche valley region is comprised of the inaccessible rear part of the Purandhar fort and its surrounding valley region and is situated about 63 km to the southeast of Pune city and 18 km from Saswad town. The total area of the valley region is about 132 sq. km. Parinche is the biggest village and a nodal place in the valley. The majority (12) of the documented groves are located in the Kaldari and Pangare zones. The size of the sacred groves has however reduced due to various human related activities that have taken place in recent years.

The biggest sacred grove in the Parinche valley belongs to Buvasaheb of Tonapewadi and spreads over an area of 4.80 hectares. The forest types are unique to the groves. Presence of key species in the sacred groves varies from region to region. Two key tree species, i.e. Terminalia bellerica and Ficus spp., are present in these sacred groves which have almost disappeared from the surrounding areas.

Large buttressed trees are another important feature of well-preserved sacred groves. The presence of these tree species indicates the vegetation of the past and also the type of potential vegetation that can be regenerated in these regions.

11th Biology Digest Chapter 1 Living world Intext Questions and Answers

Can you recall? (Textbook Page No. 01)

Whether all organism are similar? Justify your answer.
Answer:
No, all organisms are not similar.

1. Organisms on the earth exhibit great diversity.
2. Organisms are grouped as microbes, plants (autotrophs), animals (heterotrophs) and decomposers.
3. Different microbes and decomposers have various shapes and sizes.
4. Plants can be further classified on their shape, size, structure, mode of reproduction, etc. Plants also differ greatly based on the locations in which they are found, e.g. Snowy, desert, forest, aquatic, etc.
5. Even animals show a high degree of variation. They are classified as unicellular, multicellular, invertebrates, vertebrates, etc. Also, based on the environment in which they live, they are classified as terrestrial, aerial, aquatic and amphibians.

Can you tell? (Textbook Page No. 01)

Whether all organisms prepare their own food?
Answer:
No, all organisms do not prepare their own food. Organisms that prepare their own food are known as autotrophs (e.g. Green plants, certain microbes). These organisms prepare their own food in the presence of sunlight, water and carbon dioxide.

Can you recall? (Textbook Page No.01)

what is the difference between living and non-living things?
Answer:

Can we call? (Textbook Page No. 01)

Can we call reproduction as inclusive character of life?
Answer:
No, we cannot call reproduction as an inclusive character of life. Certain organisms like mules and worker bees do not reproduce and are still living. Thus, reproduction cannot be considered as an all inclusive defining characteristic of living organisms.

Can you tell? (Textbook Page No. 01)

Which feature can be considered as all-inclusive characteristic of life? Why?
Answer:
Metabolism can be considered as an all-inclusive (defining) feature of life since it is exhibited by all living organisms and does not take place in non-living things. Another all-inclusive characteristic of life is responsiveness or irritability. This is a unique property of living beings since all living beings are conscious of their surroundings.

Think about it. (Textbook Page No. 01)

(i) Can metabolic reactions demonstrated in a test tube (called ‘in vitro’ tests) be called living?
Answer:
(a) The sum total of all the chemical reactions occurring in the body is known as metabolism and no non-living object exhibits metabolism.
(b) However, metabolic reactions can be demonstrated outside the body in a test tube (cell-free medium).
(c) Thus, isolated metabolic reaction (s) outside the body of an organism, performed in a test tube is neither living nor non-living.
(d) Metabolic reactions occurring in vitro are living reactions but not living things.

(ii) Now a days patients are declared ‘brain dead’ and are on life support. They do not show any sign of self-consciousness. Are they living or non-living?
Answer:
The brain controls all life processes. Hence, when a patient is declared as ‘brain dead’, he does not carry out any of the inclusive defining characters of living things (e.g. metabolism, consciousness, etc.) and is completely dependent on machines. Since, such patients do not show any sign of self-consciousness, these patients cannot exactly be called as living.

Can you tell? (Textbook Page No. 01)

How can we study large number of organisms at a glance?
Answer:
Systematic study of organisms with the help of taxonomical aids can be used to study a large number of organisms at a glance.

Can you tell? (Textbook Page No. 03)

What are the essentials of a good herbarium?
Answer:
The essentials of a good herbarium are as follows:

1. It is essential to identify and label the collected specimen correctly.
2. Specimens should be stored in a dry place.
3. The plants are usually pressed and mounted on the sheet of paper known as herbarium sheets. Some plants are not suitable for pressing or mounting, like succulents, seeds, cones, etc. They need to be preserved in suitable liquid like formaldehyde, acetic alcohol, etc.
4. In order to preserve the specimen for longer durations, acid-free paper, special glues and inks must be used to mount the specimen so that the specimen does not deteriorate.
5. The specimens should be dried well before preparing a herbarium in order to prevent rotting of specimen.
6. It is also essential to record the date, place of collection along with detailed classification and highlighting with its ecological peculiarities, characters of the plant on a sheet.

Local names of plant specimens and name of the collector may be added. This information is given at lower right comer of sheet and is called ‘label’.

Why does the loss of biodiversity matter? (Textbook page no. 03)
Answer:

1. The loss of biodiversity is an moral and ethical issue.
2. Biodiversity helps to maintain stability in an ecosystem.
3. Humans share the environment with various other organisms and harm to these species can result in loss of biodiversity.
4. The loss of even one variety of organisms can affect the entire ecosystem. Hence, due to all these reasons, loss of biodiversity matters.

(ii) Environmental effects of ambitious projects like connecting rivers or connecting cities by constructing roads.
Answer:
Connecting rivers or connecting cities by constructing roads have the following environmental effects:
(a) They form barriers to animals.
(b) Construction of roads requires cutting down of trees and results in large scale deforestation.
(c) They occupy large land resources resulting in loss of habitat of various species.
(d) It can alter the water flow pattern and damage many ecosystems.
(e) Increase in air, water, soil and noise pollution can disturb various animals and birds, thus affecting their behavioural pattern.

(iii) Did bauxite mining in Western Ghats affect critically endangered species like – Black panther, different Ceropegia spp., Eriocaulon spp. ?
Answer:
(a) The Western Ghats, is one of the global biodiversity hotspots and retains more than 30% of all plant, aquatic, reptile, amphibian and mammal species found in India.
(b) Recently, this ecologically sensitive region has been subjected to various developmental activities that have adversely affected the flora and fauna of the region.
(c) Bauxite mining is one such activity which has had significant negative impact on the local environment. To access bauxite ore deposits, the above-ground vegetation needs to be completely removed, causing large scale deforestation. The vegetation in the adjoining area is also affected due to dumping.
(d) The major threats of this activity include vegetation loss, forest fragmentation and biodiversity loss.
(e) Since most mines fall in Eco-Sensitive Zones (ESZ), it has seriously affected the flora and fauna of the Western Ghats.
(f) Black panthers have frequently been spotted at various locations in the Western Ghats and mining in these areas can seriously affect their health and numbers.
(g) Certain species of Ceropegia and Eriocaulon that are endemic in the area have been reported to be critically endangered.
[Source: Chandore A. (2015) Endemic and threatened flowering plants of Western Ghats with special reference to Konkan region of Maharashtra. Journal of Basic Sciences. 2 (21-25)]
Hence it is most likely that bauxite mining in Western Ghats has adversely affected the critically endangered species like – Black panther, different Ceropegia spp., Eriocaulon spp.

2. Answer the following in one sentence :

Question i.
Why cations are Lewis acids ?
Answer:
Since cations are deficient of electrons they accept a pair of electrons, hence they are Lewis acids.

Question ii.
Why is KCl solution neutral to litmus?
Answer:

1. Since KCl is a salt of strong base KOH and strong acid HCl, it does not undergo hydrolysis in its aqueous solution.
2. Due to strong acid and strong base, concentrations [H₃O⁺] = [OH^–] and the solution is neutral.

Question iii.
How are basic buffer solutions prepared?
Answer:

1. Basic buffer solution is prepared by mixing aqueous solutions of a weak base like NH₄OH and its salt of a strong acid like NH₄Cl.
2. A weak base is selected according to the required pH or pOH of the solution and dissociation constant of the weak base.

Question iv.
Dissociation constant of acetic acid is 1.8 × 10^-5. Calculate percent dissociation of acetic acid in 0.01 M solution.
Answer:
Given : K_a = 1.8 x 10^-5; C = 0.01 M
Percent dissociation = ?

∴ Percent dissociation = α × 100
= 4.242 × 10^-2 × 10²
= 4.242%
Percent dissociation = 4.242%

Question v.
Write one property of a buffer solution.
Answer:
Properties (or advantages) of a buffer solution :

• The pH of a buffer solution is maintained appreciably constant.
• By addition of a small amount of an acid or a base pH does not change.
• On dilution with water, pH of the solution doesn’t change.

Question vi.
The pH of a solution is 6.06. Calculate its H⁺ ion concentration.

Question vii.
Calculate the pH of 0.01 M sulphuric acid.
Answer:
Given : C = 0.01 M H₂SO₄, pH = ?
\(\mathrm{H}_{2} \mathrm{SO}_{4(\mathrm{aq})} \longrightarrow 2 \mathrm{H}_{(\mathrm{aq})}^{+}+\mathrm{SO}_{4(\mathrm{aq})}^{2-}\)
∴ [H₃O⁺] = 2 × 0.01 = 0.02 M
PH = -log₁₀ [H₃O⁺]
= -log₁₀ 0.02
= –\((\overline{2} .3010)\)
= 2 – 0.3010
= 1.6990
pH = 1.6990.

Question viii.
The dissociation of H₂S is suppressed in the presence of HCl. Name the phenomenon.
Answer:
The weak dibasic acid H₂S is dissociated as follows :

When HCl is added, it increases the concentration of common ion H₃O⁺.
\(\mathrm{HCl}_{(\mathrm{aq})}+\mathrm{H}_{2} \mathrm{O}_{(\mathrm{l})} \rightarrow \mathrm{H}_{3} \mathrm{O}_{(\mathrm{aq})}^{+}+\mathrm{Cl}_{(\mathrm{aq})}^{-}\)
Hence by Le Chaterlier’s principle, the equilibrium is shifted from right to left, suppressing the dissociation of weak electrolyte H₂S.

Question ix.
Why is it necessary to add H₂SO₄ while preparing the solution of CuSO₄?
Answer:
CuSO₄ is a salt of strong acid H₂SO₄ and weak base Cu(OH)₂. CuSO₄ in aqueous solution undergoes hydrolysis and forms a precipitate of Cu(OH)₂ and solution becomes turbid.
CuSO₄ + 2H₂O ⇌ CU(OH)₂↓ + H₂SO₄
OR
CuSO₄ + 4H₂O ⇌ Cu(OH)₂ + 2H₃O⁺ + \(\mathrm{SO}_{4}^{2-}\)
When H₂SO₄ is added, the hydrolysis equilibrium is shifted to left hand side and Cu(OH)₂ dissolves giving clear solution.

Question x.
Classify the following buffers into different types :
a. CH₃COOH + CH₃COONa
b. NH₄OH + NH₄Cl
c. Sodium benzoate + benzoic acid
d. Cu(OH)₂ + CuCl₂
Answer:
(a) Acidic buffer (CH₃COOH + CH₃COONa)
(b) Basic buffer (NH₄OH + NH₄Cl)
(c) Acidic buffer (Sodium benzoate + benzoic acid)
(d) Basic buffer (Cu(OH)₂ + CuCl₂)
[Note : Cu(OH)₂ being insoluble is not used to prepare a buffer solution.]

3. Answer the following in brief :

Question i.
What are acids and bases according to Arrhenius theory ?
Answer:
According to Arrhenius theory :
Acid : It is a substance which contains hydrogen and on dissolving in water produces hydrogen ions (H⁺) E.g. HCl
\(\mathrm{HCl}_{(\mathrm{aq})} \rightleftharpoons \mathrm{H}_{(\mathrm{aq})}^{+}+\mathrm{Cl}_{(\mathrm{aq})}^{-}\)

Base : It is a substance which contains OH group and on dissolving in water produces hydroxyl ions (OH^–). E.g. NaOH
\(\mathrm{NaOH}_{(\mathrm{aq})} \rightleftharpoons \mathrm{Na}_{(\mathrm{aq})}^{+}+\mathrm{OH}_{(\mathrm{aq})}^{-}\)

Question ii.
What is meant by conjugate acid-base pair?
Answer:
Conjugate acid-base pair : A pair of an acid and a base differing by a proton is called a conjugate acid-base pair.

Question iii.
Label the conjugate acid-base pair in the following reactions
a. HCl + H₂O ⇌ H₃O⁺ + Cl^–
b. \(\mathrm{CO}_{3}^{2-}\) + H₂O ⇌ OH^– + \(\mathrm{HCO}_{3}^{-}\)
Answer:

Question iv.
Write a reaction in which water acts as a base.
Answer:

Since water accepts a proton, it acts as a base.

Question v.
Ammonia serves as a Lewis base whereas AlCl₃ is Lewis acid. Explain.
Answer:

• Since ammonia molecule, NH3 has a lone pair of electrons to donate it acts as a Lewis base.
• AlCl₃ is a molecule with incomplete octet hence it is electron deficient and acts as a Lewis acid.

Question vi.
Acetic acid is 5% ionised in its decimolar solution. Calculate the dissociation constant of acid.
Answer:
Given : C = 0.1 M; Dissociation = 5%, K_a=2 Percent dissociation

Dissociation constant of acid = K_a = 2.63 × 10^-4

Question vii.
Derive the relation pH + pOH = 14.
Answer:
The ionic product of water, Kw is given by,
Kw = [H₃O⁺] × [OH^–]
At 298 K, K_w = 1 × 10^-14
∴ pK_w = -log₁₀K_w = log₁₀ 1 x 10^-14 = 14
∵ [H₃O⁺] × [OH^–] = 1 × 10^-14
Taking logarithm to base 10 of both sides,
log₁₀ [H₃O⁺] + log₁₀ [OH^–] = log₁₀ 1 x 10^-14
Multiplying both the sides by -1,
-log₁₀ [H₃O⁺] -log₁₀ [OH^–] = -log₁₀ 1 x 10^-14
∵ pH = -log₁₀ [H₃O⁺]; pOH = -log₁₀ [OH^–];
pKw = – log₁₀ K_w
∴ pH + pOH = pK_w
OR pH + pOH =14

Question viii.
Aqueous solution of sodium carbonate is alkaline whereas aqueous solution of ammonium chloride is acidic. Explain.
Answer:
(A) (i) Sodium carbonate is a salt of weak acid and strong base.
(ii) In aqueous solution it undergoes hydrolysis.

(iii) Strong base dissociates completely while weak acid dissociates partially since [OH^–] > [H₃O⁺], the solution is basic.

(B) (i) Ammonium chloride is a salt of strong acid and weak base.
(ii) In aqueous solution it undergoes hydrolysis

(iii) Since [H⁺] or [H₃O⁺ ] > [OH^–] the solution is acidic.

Question ix.
pH of a weak monobasic acid is 3.2 in its 0.02 M solution. Calculate its dissociation constant.
Answer:
Given : pH = 3.2; C = 0.02 M; K_a = ?
pH = -log₁₀ [H⁺]
∴ [H⁺] = Antilog – pH
= Antilog – 3.2
= Antilog \(\overline{4} .8\)
= 6.31 × 10^-4M

K_a = cα²
= 0.02 × (0.0315)²
= 1.984 × 10^-5
Dissociation constant = K_a = 1.984 × 10^-5

Question x.
In NaOH solution [OH^–] is 2.87 × 10^-4. Calculate the pH of solution.
Answer:
Given : [OH^–] = 2.87 × 10^-4 M, pH = ?
pOH = -log₁₀ [OH^–]
= -log₁₀ 2.87 × 10^-4
= –\((\overline{4} .4579)\)
= (4 – 0.4579)
= 3.5421
∵ pH + pOH = 14
∴ pH = 14 – pOH = 14 – 3.5421 = 10.4579
pH = 10.4579.

4. Answer the following :

Question i.
Define degree of dissociation. Derive Ostwald’s dilution law for the CH₃COOH.
Answer:
(A) Degree of dissociation :
It is defined as a fraction of total number of moles of an electrolyte that dissociate into its ions at equilibrium.
It is denoted by a and represented by,
α = \(\frac{\text { number of moles dissociated }}{\text { total number of moles of an electrolyte }}\)
Or α = \(\frac{\text { Per cent dissociation }}{100}\)
∴ Per cent dissociation = α × 100

(B) Consider V dm³ of a solution containing one mole of CH₃COOH. Then the concentration of acid is, C = \(\frac{1}{V}\) mol dm³. Let α be the degree of dissociation


This is Ostwald’s dilution law.

Question ii.
Define pH and pOH. Derive relationship between pH and pOH.
Answer:
(1) pH : The negative logarithm, to the base 10, of the molar concentration of hydrogen ions, H⁺ is known as the pH of a solution.
pH = -log₁₀ [H⁺]

(2) pOH : The negative logarithm, to the base 10, of the molar concentration of hydroxyl ions, OH^– is known as the pOH of a solution.
pOH = -log₁₀ [OH^–]

Relationship between pH and pOH:
The ionic product of water, Kw is given by,
K_w = [H₃O⁺] × [OH^–]
At 298 K, K_w = 1 × 10^-14
∴ pK_w = -log₁₀K_w = log₁₀ 1 x 10^-14 = 14
∵ [H₃O⁺] × [OH^–] = 1 × 10^-14
Taking logarithm to base 10 of both sides,
log₁₀ [H₃O⁺] + log₁₀ [OH^–] = log₁₀ 1 x 10^-14
Multiplying both the sides by -1,
-log₁₀ [H₃O⁺] – log₁₀ [OH^–] = -log₁₀ 1 x 10^-14
∵ pH = -log₁₀ [H₃O⁺]; pOH = -log₁₀ [OH^–];
pK_w = – log₁₀ K_w
∴ pH + pOH = pK_w
OR pH + pOH =14

Question iii.
What is meant by hydrolysis ? A solution of CH₃COONH₄ is neutral. why ?
Answer:
Hydrolysis : A reaction in which the cations or anions or both the ions of a salt react with water to produce acidity or basicity or sometimes neutrality is called hydrolysis.

A salt of weak acid and weak base for which K_a = K_b:
Consider hydrolysis of CH₃COONH₄.

Since K_a = K_b, the weak acid CH₃COOH and weak base NH₄OH dissociate to the same extent, hence, [H₃O⁺] = [OH^–] and the solution reacts neutral after hydrolysis.

Question iv.
Dissociation of HCN is suppressed by the addition of HCl. Explain.
Answer:
The weak acid HCN is dissociated as follows :
\(\mathrm{HCN}_{(\mathrm{aq})}+\mathrm{H}_{2} \mathrm{O}_{(\mathrm{l})} \rightleftharpoons \mathrm{H}_{3} \mathrm{O}_{(\mathrm{aq})}^{+}+\mathrm{CN}_{(\mathrm{aq})}^{-}\)
The dissociation constant K_a is represented as,
K_a = \(\frac{\left[\mathrm{H}_{3} \mathrm{O}^{+}\right] \times\left[\mathrm{CN}^{-}\right]}{[\mathrm{HCN}]}\)
When HCl is added, it increases the concentration of H₃O⁺, hence in order to keep the ratio constant, then by Le Chatelier’s principle, the equilibrium is shifted from right to left, suppressing the dissociation of HCN.

Question v.
Derive the relationship between degree of dissociation and dissociation constant in weak electrolytes.
Answer:
Expression of Ostwald’s dilution law in the case of a weak electrolyte : Consider the dissociation of a weak electrolyte BA. Let V dm³ of a solution contain one mole of the electrolyte. Then the concentration of a solution is, C = \(\frac{1}{V}\)mol dm^-3. Let α be the degree of dissociation of the electrolyte.

Applying the law of mass action to this dissociation equilibrium, we have,

As the electrolyte is weak, α is very small as compared to unity, ∴ (1 – α) ≈ 1.

This is the expression of Ostwald’s dilution law. Thus, the degree of dissociation of a weak electrolyte is directly proportional to the square root of the volume of the solution containing 1 mole of an electrolyte.

Question vi.
Sulfides of cation of group II are precipitated in acidic solution (H₂S + HCl) whereas sulfides of cations of group IIIB are precipitated in ammoniacal solution of H₂S. Comment on the relative values of solubility product of sulfides of these.
Answer:
(1) In qualitative analysis, the cations of group II are precipitated as sulphides, namely HgS, CuS, PbS, etc., while cations of group IIIB are precipitated as sulphides, namely, CoS, NiS, ZnS.

(2) The sulphides of group II have extremely low solubility product (K_sp) about 10^-29 to 10^-53 while the sulphides of group IIIB have slightly higher K_sp values about 10^-20 to 10^-23.

(3) In group II, sulphides are precipitated by adding H₂S in acidic solution while in IIIB group they are precipitated in a basic solution like ammonical solution.

(4) In acidic medium due to common ion H⁺, H₂S is dissociated to very less extent but gives sufficient S^2- ion to exceed solubility product of group II sulphides of cations and precipitate them.
\(\mathrm{HCl}_{(\mathrm{aq})} \longrightarrow \mathrm{H}_{(\mathrm{aq})}^{+}+\mathrm{Cl}_{(\mathrm{aq})}^{-} ; \mathrm{H}_{2} \mathrm{~S}_{(\mathrm{aq})} \rightleftharpoons 2 \mathrm{H}_{(\mathrm{aq})}^{+}+\mathrm{S}_{(\mathrm{aq})}^{2-}\)

(5) In basic medium, H⁺ from H₂S are removed by OH^– in solution, or by NH₄OH, increasing the dissociation of H₂S and concentration of S^2-, so that IP > K_sp.

(6) Therefore group II cations are precipitated in an acidic medium while cations of group IIIB are precipitated in ammonical solution.

Question vii.
Solubility of a sparingly soluble salt get affected in presence of a soluble salt having one common ion. Explain.
Answer:
Consider the solubility equilibrium of a sparingly soluble salt, AgCl.
\(\mathrm{AgCl}_{(\mathrm{s})} \rightleftharpoons \mathrm{Ag}_{(\mathrm{aq})}^{+}+\mathrm{Cl}_{(\mathrm{aq})}^{-}\)
The solubility product, K_sp is given by,
K_sp = [Ag⁺] × [Cl^–]
Consider addition of a strong electrolyte AgNO₃ with a common ion Ag⁺.
\(\mathrm{AgNO}_{3(\mathrm{aq})} \longrightarrow \mathrm{Ag}_{(\mathrm{aq})}^{+}+\mathrm{NO}_{3(\mathrm{aq})}^{-}\)
The concentration Ag⁺ in the solution is increased, hence by Le Chatelier’s principle the equilibrium of AgCl is shifted to left hand side since the value of K_sp is constant.
Thus in the presence of a common ion, the solubility of a sparingly soluble salt is suppressed.

Question viii.
The pH of rain water collected in a certain region of Maharashtra on particular day was 5.1. Calculate the H₃O⁺ ion concentration of the rain water and its percent dissociation.
Answer:
Given : pH = 5.1, [H₃O⁺] = ?
PH = -log₁₀ [H₃O⁺]
∴ log₁₀ [H₃O⁺] = -pH
∴ [H₃O⁺] = Antilog – pH
= Antilog – 5.1
= Antilog \(\overline{6} .9\)
= 7.943 × 10^-6 M
(H₃O⁺ in rainwater is due to dissolved gases, CO₂, SO₂, etc. forming acids which dissociate giving H₃O⁺ and acidity to rainwater.)
[H₃O⁺] = 7.943 × 10^-4 M

Question ix.
Explain the relation between ionic product and solubility product to predict whether a precipitate will form when two solutions are mixed?
Answer:
If ionic product and solubility product are indicated by IP and K_sp respectively then,
(I) When IP = K_sp, the solution is saturated.
(II) When IP > K_sp, the solution is supersaturated and hence precipitation will occur, when two solutions are mixed.
(Ill) When IP < K_sp, the solution is unsaturated and precipitation will not occur, when two solutions are mixed.

Question 1.
Suppose that pH of monobasic and dibasic acid is the same. Does this mean that the molar concentrations of both acids are identical ?
Answer:
Even if monobasic acid and dibasic acid give same pH, their molar concentrations are different. One mole of monobasic acid like HCl gives 1 mol of H⁺ while one mole of dibasic acid gives 2 mol of H⁺ in solution. Hence the concentration of dibasic acid will be half of the concentration of monobasic acid. For example, for same pH. [Monobasic acid] = [Dibasic acid]/2

Question 2.
How does pH of pure water vary with temperature ? Explain.
Answer:
Since the increase in temperature, increases the dissociation of water, its pH decreases.

Question 1.
How is the ionization of NH₄OH suppressed by addition of NH₄Cl to the solution of NH₄OH ?
Answer:
Ionisation of NH₄OH is represented as follows :
\(\mathrm{NH}_{4} \mathrm{OH}_{(\mathrm{aq})} \rightleftharpoons \mathrm{NH}_{4(\mathrm{aq})}^{+}+\mathrm{OH}_{(\mathrm{aq})}^{-}\)
It has ionisation constant,
K_b = \(\frac{\left[\mathrm{NH}^{4+}\right] \times\left[\mathrm{OH}^{-}\right]}{\left[\mathrm{NH}_{4} \mathrm{OH}\right]}\)
K_b has constant value at constant temperature. When strong electrolyte NH₄Cl is added to its solution, it dissociates completely.
\(\mathrm{NH}_{4} \mathrm{Cl}_{(\mathrm{aq})} \longrightarrow \mathrm{NH}_{4(\mathrm{aq})}^{+}+\mathrm{Cl}_{(\mathrm{aq})}^{-}\)
Due to common ion \(\mathrm{NH}_{4}^{+}\), by Le Chatelier’s principle, the equilibrium is shifted from right to left, suppressing the ionisation of NH₄OH.

• The entire business centres around its object clause.
• Object clause of the Memorandum of Association defines the area beyond which the company cannot do anything.
• It determines the powers of the company.
• It helps the stakeholders to know what is its permitted range of operation.
• A company is governed by Memorandum of Association and any act beyond it shall be considered as ultra-vires.
• Hence, Memorandum of Association defines the limitations of the power of the company.

Question 2.
Ultra-vires acts are null and void.
Answer:

• A Memorandum of Association of a company is a basic charter of the company.
• If a company departs from its Memorandum of Association such an act is ultra-vires.
• The doctrine of ultra vires is a fundamental rule of company law.
• An act legally in itself but not authorized by the object clause of Memorandum of Association of a company is ultra-vires.
• Hence if the company does an act or enters into a contract beyond the powers of the company then the act is said to be null and void.
• The company cannot sue on an ultra-vires transaction or it cannot be sued.
• Thus, I agree with the above statement.

Question 3.
Contents of Articles can be altered.
Answer:

• As per section 2(2) of the companies Act, 1956 ‘Articles’ means Articles of Association of a company as originally framed or as altered from time to time in pursuance of any previous companies’ law or of this Act.

• The articles, being the internal regulations of a company can be altered easily.
• The articles are required to be altered from time to time as per changes made by the government in the company law or as per changing situations in the corporate sector.
• Thus, the Articles of Association can be altered by passing a ‘Special Resolution’ at a general meeting.

Question 4.
The doctrine of Indoor Management protects outsiders who are unaware of the correctness of the internal proceedings of a company.
Answer:

• The doctrine of Indoor Management states that a person entering into a contract with the company need not inquire whether the company has followed the internal processing.
• It is assumed that the company acts as per the Memorandum of Association and Articles of Association.
• Because certain information which is internal to a company cannot be known to outsiders.
• So the doctrine of Indoor Management protects the interest of the outsider when the act is based on the Memorandum of Association and Articles of Association.

Question 5.
A prospectus is an important document issued by a public company.
Answer:

• A prospectus usually is in the form of a statement giving all material information about the company and showing its future prospectus.
• It aims at inviting investors to subscribe to its shares and debentures.
• It is a must for every public company to prepare its prospectus.
• It is through the prospectus that the prospective investors know the details of the shares offered by the company.

• All detailed information about a company like its business management, financial structure, etc., are provided in the prospectus.
• The main idea to issue a prospectus is to collect capital for the company from the general public.
• It should contain true, fair, and correct information.
• Hence, the prospectus is very important for a public company.

Question 2.
Define Memorandum of Association. Explain briefly its features.
Answer:
Definition:
As per section 2(28) of the companies Act 1956 “Memorandum of Association means the Memorandum of Association of a company as originally framed or altered from time to time in pursuance of any previous company laws or of this Act”.
As such this definition does not state exactly the scope, use, and importance of memorandum in a company.

• Lord Cairns observed that – “The memorandum of association is a charter and defines the limits of the powers of a company. The memorandum contains the fundamental conditions upon which alone the company is allowed to incorporate”.
• Lord Macmillan states that – “The purpose of the memorandum is to enable the shareholders, creditors and those who deal with the company to know what is its permitted range of enterprise”.

Meaning:
In simple words, the Memorandum of Association of a company means

• a basic or fundamental primary document of a company.
• a charter or constitution of a company
• no company can be incorporated without the Memorandum of Association.
• It lays down the range of its activities.
• It is a public document and can be inspected by those who deal with the company.

Features of Memorandum of Association:
The following are the features of the Memorandum of Association:

• Memorandum of Association states the nature of business activities to be conducted by the company.
• It informs about the scope of activities of the company.
• It is prepared by promoters of the company.
• It is signed by at least 7 persons in the case of a public company and 2 persons in the case of a private company.
• It is submitted to the registrar of companies for registration.
• All companies must prepare their own Memorandum of Association.
• It defines the relationship between the company and outsiders.
• It is an unalterable charter of the company.
• It is a public document.

Question 3.
What are Articles of Association? Explain briefly its content.
Answer:
Articles of Association contain rules and regulations regarding the management of the company’s internal affairs.

• It defines the powers, duties, and rights of managers, officers, and the board of directors.
• It establishes a relationship between the company and its members.

Contents of Articles of Association:

• The amount of share capital and different classes of shares

11th English Digest Chapter 4.3 Extracts of Drama – An Enemy of the People Textbook Questions and Answers

Character:

Question 1.
Mayor Peter Stockmann is a contrast to Dr. Thomas Stockmann. Justify.
Answer:
There are lots of good things you can say about Dr. Stockmann, the protagonist of ‘An Enemy of the People’. He is an idealist and a man having great love and care for his family. He is generous with his neighbors and truly cares for his fellow men. Despite his troubles, he wishes to make the world a better place. Most importantly, the doctor is a man of principles willing to fight for justice no matter what it costs.

On the contrary, Mayor Peter Stockmann, his brother is a practical man. He is the antagonist in the play who is less worried about the common men in the city. Throughout the play, the Mayor, Stockmann mercilessly tries to ruin his brother’s life in order to keep the truth from being revealed. He hardly shows any affinity towards his brother. He never shows any feeling of guilt for the fact that he’s totally messing up the life of a family member.

Question 2.
Write the character sketch of Dr. Stockmann.
Answer:
Dr. Stockmann is the brother of the Mayor, Peter Stockmann and the protagonist/hero of the play. He is a practising medical doctor and the medical officer of the town baths. He is an ideal person who has great love for family, fellow citizens and social values. Dr. Stockmann believes strongly in individual freedom and the right of every man to express himself freely.

He is a man of morality and truth and is ready to fight against injustice. He tries to raise his voice against the hypocritical ways of his brother and the members of conservative government. The play revolves around his struggle to give justice to common men of the city. Finally, his fruitless efforts lead him to such misfortune to ruin everything in his profession and life. However, he is not ready to give up his efforts for truth. We see him as a man of patience and strength when he remarks – “The strongest man in the world is he who stands alone!”

3. Read the given extract.

Question (i)
Complete the following table. (Answers are given directly in bold)
Answer:

Question (ii)
Match the column ‘A’ with column ‘B’

Answer:

Plot:

Question 1.
Describe the climax scene in your own words. Write your comments on it.
Answer:
In the final scene, Dr. Stockmann realizes that no one is going to support him to publish the article as no one is ready to take any step against the Mayor. So, Stockmann asks Hovstad to give him back his papers (article). He announces in front of the Mayor that he will read out the article in a mass meeting for everybody to hear the voice of truth. But, the Mayor assures him that no one will lend him a hall in the city to do this.

Billing and Hovstad have also the same opinion. Mrs. Stockmann feels shameful to know the fact that no one is willing to give her husband a hall. She is rather shocked to know that everyone has turned against her husband. Dr. Stockmann is ready to hire a drum to walk on the city streets reading the article. It shows his determination to reveal the truth at any cost. All the family members are ready to stand with Dr. Stockmann in his sincere efforts to purify the society.

Question 2.
Describe in your own words the incident when Hovstad’s real intention to help Dr. Stockmann is exposed.
Answer:
When Dr. stockmann reached Hovstad’s office, he notices the Mayor’s stick and hat and suspects him of hiding in the next room. Dr. Stockmann enquired if Hovstad was going to publish the article in ‘People’s Messenger’. Hovstad answered him that he had to wait for publishing the article.

Hovstad didn’t refuse him but was not ready to publish it. He was under the influence of the Mayor and had personal interest. In addition, both Billing and Aslaksen supported the editor. Dr. Stockmann approached to Aslaksen for requesting him to atleast print the article as a pamphlet. However he denied doing so. Finally, Hovstad refused to print the article saying it would ruin doctor’s family. Here, the Dr. realized Hovstad’s real intention of not printing the article as he was doing everything to protect himself.

3. Write down the consequences of the following occurrences, with the help of the play.

Question (a)
Dr. Thomas Stockmann wants an article exposing social evils to be printed in the newspaper.
Answer:
Dr. Stockmann was an idealist and a lover of truth. When he came across the unhygienic condition of the baths which was a direct threat to the health of the people, he decided to publish the article in the newspaper exposing the Mayor and his cronies. This would directly affect the ruling government to lose their seats. In addition, it would raise public outcry against the social injustice of the Mayor and his stakeholders had to pay a large amount to rectify the issue.

Question (b)
The Mayor, Peter Stockmann persuades Mr. Hovstad and Mr. Billing from printing the article.
Answer:
The Mayor entered Hovstad’s office through the back doors. He didn’t want to let Dr. Stockmann know about his visit to Hovstad. When he met Hovstad and Billing, he told them that Dr. Stockmann is a headstrong man and had some wrong informations about the condition of the baths.

He also praised both Hovstad and Billing and assured them that he had another article to publish which would clear the doubts of all regarding the baths. He indirectly assured them to have their favour in this matter if they supported him. As Dr. Stockmann came to know about the Mayor’s visit to Hovstad’s office to persuade them, he was of the firm opinion that they would not publish his article.

Question (c)
Aslaksen declares that he would not print Dr. Stockmann’s article.
Answer:
As the Mayor told Aslaksen his idea of raising the money from the small tradesmen, Aslaksen thought that Dr. Stockmann’s idea of extensive alternation of the baths was unrealistic. So he decided not to print the article in the newspaper and save the small tradesmen from this unnecessary burden. As Aslaksen denied printing the article, Dr. Stockmann assured them that he would read the article in the mass meeting or raise the issue on the streets of the city. He would anyway expose the ruling government and give justice to common men.

Question (d)
Katherine encourages Dr. Stockmann to proceed in his attempts in the cause of public attempts.
Answer:
When the Mayor and his supporter opposed Dr. Stockmann, Mrs. Stockmann felt shameful that all of them turned against her husband. She put her arm onto his neck and told him that she was ready to stand with him. She encouraged him not to give up his idea and she and her children would help him in his mission. She finally promised to support him till the end. She added that her children Morten, Ejlif and Petra would follow him on the streets of the city.

Setting:

Question 1.
The setting of the act is the office of the newspaper ‘The Herald’. Explain how it is the proper background for the theme of the play.
Answer:
This act is set in the editor’s room at the office of ‘People’s Messenger’. One door leads to the printing office and another to the rest of the offices. There is a large table in the middle covered with books, papers and newspapers and there is a desk at the window. The room is described as ‘dingy and cheerless’.

The setting of the play is appropriate to the theme as the single door opening shows that truth is the only way to be followed by everyone. The dingy and clumsy atmosphere and old furniture urge need of change and renovation in the existing situation. The table covered with books and newspapers is a symbol of chaos and anarchy in the government.

The window stands for a ray of hope in the darkness of injustice. A few closed chairs symbolize time to wind-up prevailing conservative government and bring in new liberal governance. The glass panels stand for transparency and clarity in every section of the government.

Question 2.
Explain the use of the following property in the development of the play.
Answer:
(a) Hat – Hat plays an important role in the development of the play. It stands for the city’s authority, ‘the Mayor’ as it was a part of the official uniform. When Dr. Stockmann put on the hat, he told his brother that the entire city was in his hand. He also added that with that supreme power he would throw him off the existing government. Dr. Stockmann saw the Mayor’s hat in the editor’s room and could realize that the Mayor was hiding in the next room, listening his conversation with the editor. This made him understand the Mayor’s plot of ruining his article.

(b) Stick – The stick at certain instances was a symbol of assertiveness, commitment, new ideas or sticking to the old things. The stick in Dr. Stockmann’s hand suggests his assertiveness, commitment and new ideas in the existing government with the support of everyone. But the stick in the Mayor’s hand, suggests that the whole situation was groomed by him to turn against Dr. Stockmann. The stick in the hand of the Mayor also proves his authority and command over other people.

(c) An envelope containing the letter – The envelope of the letter focuses over the issue of grievance which everyone keeps by hiding a secret. Dr. Stockmann took various efforts to expose the issue but finally Hovstad returned the envelope to him, which suggests how everyone tried to conceal the burning issue. The issue needed immediate attention, but was hidden from the public as the letter was hidden by the envelope.

3. Explain the following statements with reference to the context.

Question (a)
And then, once the ring is broken, we’ll get to work and show the public every day just how incompetent the Mayor is!
Answer:
When both Hovstad and Billing read Dr. Stockmann’s article, they were shocked to know that the article would bring a revolution in the city. Hovstad was ready to publish that article the next day in ‘People’s Messenger’. Billing thought that if the Mayor didn’t like it then it would be a great trouble for them. But Hovstad was ready to take the risk as the problem was acute.

The Mayor would be in trouble from either by the small tradesmen and the householders’ association or by the shareholders in the bath. Anyhow the ring would be a broken and they would get a chance everyday to expose the Mayor through the newspaper and the entire government would go in the hands of the liberals.

Question (b)
From now on The Herald shall be my artillery.
Answer:
Billing, Aslaksen, Hovstad and Dr. Stockmann were discussing about the article. Hovstad was ready to publish the article in the ‘People’s Messenger’ on the next day only. Seeing this Aslaksen agreed with Hovstad to print whatever he wished to print. Dr. Stockmann was of the opinion that it would disrupt on the entire system.

Dr. Stockmann told them that the Mayor and his cronies tried to persuade him by all means but he was determined to publish the article at any cost. Now, Dr. Stockmann considered ‘People’s Messenger’ as his sheet-anchor (additional support)to use it as an artillery to attack on the Mayor with one article after another.

Question (c)
You ought to be ashamed of yourself.
Answer:
Petra visited Hovstad and she told him that she could not translate the novel he had given her. Hovstad asked the reason why she could not translate that book. She answered that the book was unrealistic and she didn’t find it to be read by the common men. At that time, Petra came to know Hovstad’s original intention not printing her father’s article revealing the truth. She thought him as a loyal person but he turned a traitor. So she said that he ought to be ashamed of himself.

Question (d)
Because your father can’t do without my help.
Answer:
Petra did not wish to translate the book as it was unrealistic. When she asked Hovstad about her father’s article, Hovstad told her that he was not going to print the article. She sensed the intention of Hovstad and his behaviour. She did not like his way of looking at the truth. She got upset when Hovstad told her that she was fighting against it as it was only a matter of her father. She became furious as she heard his remarks that her father couldn’t do anything without his help. She got to know the attitude of Hovstad to support the Mayor in the issue.

Question (e)
And it’s by no means the small sacrifice the town will have to make.
Answer:
The Mayor tried hard to persuade Aslaksen and Hovstad that they should not support Dr. Stockmann in his attempts to publish the article as it was not in favour of the small tradesmen and the householders. If the Mayor would go for the extensive alteration of the baths, the town would have to sacrifice. It would incur great expenditure on the municipal.

As a result, they would have to put extra burden of taxes over the tradesmen and commoners. In addition, the baths would be shut down for two years. In such condition, the householders would have to suffer a lot. Eventually, the city would have to be ready to make the sacrifice but Aslaksen was in no mood to put the additional burden over the tradesmen and householders.

Match the pairs.

Answer:

3. Give reasons

Question i.
Haloarenes are less reactive than haloalkanes.
Answer:
Haloarenes (Aryl halides) are less reactive than (alkyl halides) haloalkanes due to the following reasons :

(1) Resonance effect : In haloarenes, the electron pairs on halogen atom are in conjugation with 7r-electrons of the benzene ring. The delocalization of these electrons C-Cl bond acquires partial double bond character.

Due to partial double bond character of C-Cl bond in aryl halides, the bond cleavage in haloarene is difficult and are less reactive. On the other hand, in alkyl halides, carbon is attached to chlorine by a single bond and it can be easily broken.

(2) Aryl halides are stabilized by resonance but alkyl halides are not. Hence, the energy of activation for the displacement of halogen from aryl halides is much greater than that of alkyl halides.

(3) Different hybridization state of carbon atom in C-X bond :
(i) In alkyl halides, the carbon of C-X bond is sp³-hybridized with less 5-character and greater bond length of 178 pm, which requires less energy to break the C-X bond.

(ii) In aryl halides, the carbon of C-X bond is sp³-hybridized with more 5-character and shorter bond length which requires more energy to break C-X bond. Therefore, aryl halides are less reactive than alkyl halides.

(iii) Polarity of the C-X bond : In aryl halide C-X bond is less polar than in alkyl halides. Because sp³-hybrid carbon of C-X bond has less tendency to release electrons to the halogen than a sp³-hybrid carbon in alkyl halides. Thus halogen atom in aryl halides cannot be easily displaced by nucleophile.

(2) Aryl halides are extremely less reactive towards nucleophilic substitution reactions.
Answer:
Aryl halides are extremely less reactive towards nucleophilic substitution reaction due to the following reasons : (1) Resonance effect : In haloarenes, the electron pairs on halogen atom are in conjugation with 7r-electrons of the benzene ring. The delocalization of these electrons C-Cl bond acquires partial double bond character.

Due to partial double bond character of C-Cl bond in aryl halides, the bond cleavage in haloarene is difficult and are less reactive towards nucleophilic substitution.

(2) Sp² hybrid state of C : Different hybridization state of carbon atom in C-X bond : In aryl halides, the carbon of C-X bond is sp²-hybridized with more 5-character and shorter bond length of 169 pm which requires more energy to break C-X bond. It is difficult to break a shorter bond than a longer bond, in alkyl chloride (bond length 178 pm) therefore, aryl halides are less reactive towards nucleophilic substitution reaction.

(3) Instability of phenyl cation : In aryl halides, the phenyl cation formed due to self ionisation will not be stabilized by resonance which rules out possibility of S_N1 mechanism. Also backside attack of nucleophile is blocked by the aromatic ring which rules out S_N2 mechanism. Thus cations are not formed and hence aryl halides do not undergo nucleophilic substitution reaction easily.

(4) As any halides are electron rich molecules due to the presence of re-bond, they repel electron rich nucleophilic, attack. Hence, aryl halides are less reactive towards nucleophilic substitution reactions. However, the presence of electron withdrawing groups at o/p position activates the halogen of aryl halides towards substitution.

(3) Aryl halides undergo electrophilic substitution reactions slowly.
Answer:
Aryl halides undergo electrophilic substitution reactions slowly and it can be explained as follows :

(1) Inductive effect : The strongly electronegative halogen atom withdraws the electrons from carbon, atom of the ring, hence aryl halides show reactivity towards electrophilic attack.

(2) Resonance effect : The resonating structures of aryl halides show increase in electron density at ortho and para position, hence it is o, p directing.

The inductive effect and resonance effect compete with each other. The inductive effect is stronger than resonance effect. The reactivity of aryl halides is controlled by stronger inductive effect and o, p orientation is controlled by weaker resonating effect.

The attack of electrophile (Y) on haloarenes at ortho and para positions are more stable due to formation of chloronium ion. The chloronium ion formed is comparatively more stable than other hybrid structures of carbonium ion.

(4) Reactions involving Grignard reagent must be carried out under anhydrous condition.
Answer:
(1) Grignard reagent (R Mg X) is an organometallic compound. The carbon-magnesium bond is highly polar and magnesium halogen bond is in ionic in nature. Grignard reagent is highly reactive.

(2) The reactions of Grignard reagent are carried out in dry conditions because traces of moisture may spoil the reaction and Grignard reagent reacts with water to produce alkane. Hence, reactions involving Grignard reagent must be carried out under anhydrous condition.

(5) Alkyl halides are generally not prepared by free radical halogenation of alkane.
Answer:
(1) Free radical halogenation of alkane gives a mixture of all different possible Monohaloalkanes as well as polyhalogen alkanes.
(2) In this method, by changing the quantity of halogen the desired product can be made to predominate over the other
products. Hence, alkyl halides are generally not prepared by free radical halogenation of alkane.

Question ii.
Alkyl halides though polar are immiscible with water.
Answer:
(1) In alkyl halide, the halogen atom is more electronegative than carbon atom, the C – X bond is polar.
(2) Though alkyl halide is polar, it is insoluble in water because alkyl halide is not able to form hydrogen bonds with water. Attraction between alkyl halide molecule is stronger than attraction between alkyl halide and water.

(2) C-F bond in CH₃F is the strongest bond and C-I bond in CH₃I is the weakest bond. Explain.
Answer:
(1) Methyl fluoride (CH₃F) is highly polar molecule and has the shortest C-F bond length (139 pm) and the strongest C-F bond due to greater overlap of orbitals of the same principal quantum number i.e., overlap of 2sp³ orbital of carbon with 2pz orbital of fluorine.
(2) Methyl iodide (CH₃I) is much less polar and has the longest (C-I) bond length (214 pm) and the weakest C-I bond due to poor overlap of 2sp³ orbital carbon with 5pz orbital of iodine i.e., 2sp³ orbital of carbon cannot penetrate into larger p-orbitals.

(3) The boiling point of alkyl iodide is higher than that of alkyl fluoride.
Answer:
For a given alkyl group, the boiling point increases with increasing atomic mass of the halogen, because magnitude of van der Waals force increases with increase in size and mass of halogen. Therefore, boiling point of alkyl iodide is higher than that of alkyl fluoride.

(4) The boiling point of isopropyl bromide is lower than that of it-propyl bromide.
Answer:
For isomeric alkyl halides (isopropyl bromide and n-propyl bromide), the boiling point decreases as the branching increases, surface area decreases on branching and van der Waals forces decrease, therefore, the boiling point of isopropyl bromide is lower than that of n-propyl bromide.

(5) p-Dichlorobenzene has mp. higher than those of o-and rn-isomers.
Answer:
p-Dichlorobenzene has higher melting point than those of o-and m-isomers. This is because of its symmetrical structure which can easily fits in crystal lattice. As a result intermolecular forces of attraction are stronger and therefore greater energy is required to overcome its lattice energy.

Question iii.
Reactions involving Grignard reagent must be carried out under anhydrous conditions.

Question iv.
Alkyl halides are generally not prepared by free radical halogenation of alkanes.
Answer:
(1) Direct fluorination of alkanes is highly exothermic, explosive and invariably leads to polyfluorination and decomposition of the alkanes. It is difficult to control the reaction.
(2) Direct iodination of alkanes is highly reversible and difficult to carry out.
(3) In direct chlorination and bromination, the reaction is not selective. It can lead to different isomeric monohalogenated alkanes (alkyl halides) as well as polyhalogenated alkanes.
Hence, halogenation of alkanes is not a good method of preparation of alkyl halides.

4. Distinguish between – S_N1 and S_N2 mechanism of substitution reaction ?
Answer:

5. Explain – Optical isomerism in 2-chlorobutane.
Answer:
(1) 2-Chlorobutane contains an asymmetric. carbon atom (the starred carbon atom) which is attached to four different groups, i.e., ethyl (-CH₂ – CH₃), methyl (CH₃), chloro (Cl) and hydrogen (H) groups.

(2) Two different arrangements of these groups around the carbon atom are possible as shown in the figure. Hence, it exists as a pair of enanti¬omers. The two enantiomers are mirror images of each other and are not superimposable.

(3) One of the enantiomers will rotate the plane of plane-polarized light to the left hand side and is called the laevorotatory isomer (/-isomer). The other enantiomer will rotate the plane of plane-polarized light to the right hand side and is called the dextrorotatory isomer (d-isomer).

(4) Equimolar mixture of the d- and the 1-isomers is optically inactive and is called the racemic mixture or the racemate (dl-mixture). The optical inactivity of the racemic mixture is due to external compensation.

Question iii.
Observe the following and answer the questions given below.

a. Name the type of halogen derivative
b. Comment on the bond length of C-X bond in it
c. Can react by S_N1 mechanism? Justify your answer.
Answer:
a. Vinyl halide
b. C – X bond length shorter in vinyl halide than alkyl halide. Vinyl halide has partial double bond character due to resonance.

In vinyl halide, carbon is sp hybridised. The bond is shorter and stronger and the molecule is more stable.

c. Yes, It reacts by S_N1 mechanism. S_N1 mechanism involves formation of carbocation intermediate. The vinylic carbocation intermediate formed is resonance stabilized, hence S_N1 mechanism is favoured.

Question 10.2 : (Textbook page 216)

Arrange the following compounds in order of increasing boiling points : bromoform, chloromethane, dibromomethane, bromomethane.
Answer:
The comparative boiling points of halogen derivatives are mainly related with van der Waals forces of attraction which depend upon the molecular size. In the present case all the compounds contain only one carbon. Thus the molecular size depends upon the size of halogen and number of halogen atoms present.

Thus increasing order of boiling point is, CH₃CI < CH₃Br < CH₂Br₂ < CHBr₃

Question 1.
Alkyl halides, when treated with alcoholic solution of silver nitrite, give nitroalkanes whereas with sodium nitrite they give alkyl nitrites. Explain.
Answer:
Nitrite ion is an ambident nucleophile, which can attack through ‘O’ or ‘N’.

Both nitrogen and oxygen are capable of donating electron pair. C – N bond, being stronger than N – O bond, attack occurs through C atom from alkyl halide forming nitroalkane.

However, sodium nitrite (NaNO₂) is an ionic compound and oxygen is free to donate pair of electrons. Hence, attack occurs through oxygen resulting in the formation of alkyl nitrite.

Allylic and benzylic halides show high reactivity towards the S_N1 mechanism than other primary alkyl halides. Explain.
Answer:
In allylic and benzylic halide, the carbocation formed undergoes stabilization through the resonance. Hence, allylic and benzylic halides show high reactivity towards the S_N1 reaction. The resonating structures are

Resonance stabilization of allylic carbocation

Resonance stabilization of benzylic carbocation

Question 10.5 : (Textbook page 224)

Which of the following two compounds would react faster by SN2 mechanism and Why?

Answer :
In S_N2 mechanism, a pentacoordinate T.S. is involved. The order of reactivity of alkyl halides towards S_N2 mechanism is.
Primary > Secondary > Tertiary, (due to increasing crowding in T.S. from primary to tertiary halides.
1- Chlorobutane being primary halide will react faster by S_N2 mechanism, than the secondary halide 2- chlorobutane.)

Question 1.
Conversion of chlorobenzene to phenol by aqueous sodium hydroxide requires high temperature of about 623K and high pressure. Explain.

Answer:
Due to the partial double bond character in chlorobenzene, the bond cleavage in chlorobenzene is difficult and is less reactive. Hence, during the conversion of chlorobenzene to phenol by a question NaOH requires high temperature & high pressure.
