Questions with Answers

Q1. Which types of bonds or interactions are found in the α-helix of protein?
(a) Ionic bond
(b) Covalent interaction
(c) H-bond
(d) Banana bond

Solution 1.
Ans. (c)
Sol. The alpha helix structure of proteins is primarily stabilized by hydrogen bonds. These weak bonds form between the carbonyl oxygen (𝐶 = 𝑂) of one amino acid and the amide hydrogen (𝑁𝐻) of another amino acid that is four residues further down the polypeptide chain, creating the characteristic helical shape.

Q2. What is the correct sequence of increasing reactivity of the following compounds towards nucleophilic
addition reaction?
(A) Ethanal
(B) Propanone
(C) Propanal
(D) Butanone
Choose the correct answer from the options given below:
(a) (A), (B), (C), (D)
(b) (D), (B), (C), (A)
(c) (A), (C), (B), (D)

S2.
Ans. (b)
Sol. Aldehydes are most reactive towards NAR due to the highly electrophilic centre. Ethanal is more than propanal due to a less hindered centre.
NAR: D < B < C < A

Q6. The unit of 𝐸𝑐𝑒𝑙𝑙 is
(a) V 𝑚−1
(c) 𝑉
(b) 𝑆 𝑐𝑚−1
(d) S 𝑐𝑚−2 𝑚𝑜𝑙−1

S6.
Ans. (c)
Sol. 𝐸𝑐𝑒𝑙𝑙 is the electromotive force (cell potential), whose unit is volt (V).

Q7. Which of the following compounds will not give azo coupling reaction with benzene diazonium chloride?
(a) Nitrobenzene
(b) Aniline
(c) o-Toluidine
(d) Phenol

S7.
Ans. (a)
Sol. Azo coupling reactions typically occur between a diazonium salt (like benzene diazonium chloride) and an electron-rich aromatic compound. However, electron-withdrawing groups (such as nitro groups) can prevent this reaction. Nitrobenzene: The nitro group is an electron-withdrawing group, which makes the aromatic ring less reactive toward nucleophilic substitution.

Q8. Arrange the following compounds in increasing order
of their acidic strength:
(A) 3-nitrophenol
(B) 3,5-Dinitrophenol
(C) 2,4,6 -Trinitrophenol
(D) Phenol
Choose the correct answer from the options given below
(a) (D), (C), (B), (A)
(b) (C), (A), (B), (D)
(c) (D), (A), (B), (C)
(d) (A), (B), (C), (D)

Acidic strength
(A), -I of NO2
(B), -I from 2 – NO2 groups
(C), Highly stabilised negative charge due to 3 -NO2 groups K-D<A<B<C

Ans. (c)

-M, -I
