NEET levelSingle correct optionDifficulty 1 of 3nc093

Nitrobenzene on reduction with $Sn / HCl$ gives

Aazobenzene
BN-phenylhydroxylamine
Chydrazobenzene
Daniline

Answer: D

In strongly acidic medium with a metal such as Sn or Fe, the nitro group is reduced fully to the amino group:

C X_{6} H X_{5} NO X_{2}

to

C X_{6} H X_{5} NH X_{2}

. The other three are intermediates or products in neutral or alkaline media.
