2) Zn/NH${}_4$Cl	b) Azobenzene
3) Zn/alc. KOH	c) Hydrazobenzene
4) LiAlH${}_4$	d) Aniline

• A. 1-d, 2-a, 3-c, 4-b
• B. 1-d, 2-c, 3-a, 4-b
• C. 1-d, 2-a, 3-b, 4-c
• D. 1-b, 2-a, 3-d, 4-c

Answer 1

The correct option is A 1-d, 2-a, 3-c, 4-b

Nitrobenzene can be reduced by using various products.
The products of reduction depending on the reducing agent used.

1) Reduction of nitrobenzene with zinc in presence of HCl gives aniline.

2) Reduction of nitrobenzene with zinc in presence of ammonium chloride gives phenyl hydroxylamine.

3) Reduction of nitrobenzene with zinc in presence of alcoholic potassium hydroxide gives hydrazobenzene.

4)Reduction of nitrobenzene with lithium aluminum hydride gives azobenzene.

Option A is correct.
