Question 1
1 / -0

How many primary amines are possible with the formula C₄H₁₁N?

A
1

B
2

C
3

D
4

Solution

Four (n-butylamine, isobutylamine, sec-butylamine and tert-butylamine)
Question 2
1 / -0

Which of the following form the weakest hydrogen bond?

A
Carboxylic acids

B
Alcohols

C
Primary amines

D
Primary amides

Solution

The strength of H-bonds decreases in the following order.

Primary amides > Carboxylic acids > Alcohols > Primary amines

Thus, primary amines have the weakest H-bonds.
Question 3
1 / -0

Phenyl diazonium salts form azo dye with

1. aniline
2. phenol
3. N, N-dimethyl aniline
4. anisole

A
1, 2 and 3

B
1, 2 and 4

C
1, 3 and 4

D
2, 3 and 4

Solution

PhN ≡ N + is a weak electrophile that undergoes diazocoupling only with rings activated by -OH, -NH₂, -NHR or -NR₂. The ring is not sufficiently activated by -OCH₃ and hence, anisole does not form azodye.
Question 4
1 / -0

Aromatic nitriles (ArCN) are not prepared by the reaction

A
ArX + KCN

B
ArN₂Cl + CuCN

C
ArCONH₂ + P₂O₅

D
ArCONH₂ + SOCl₂

Solution

Aryl halides do not react with KCN to form aryl cyanides, i.e.
