The reduction of nitro compounds is most preferred in the presence of

A

Pd/`H_2` in ethanol

B

Sn + HCl

C

Linely divided Ni

D

iron scrap and HCl

Text Solution

Verified by Experts

The correct Answer is:
D
Reduction with iron scrap and hydrochloric acid is preferred because `FeCl_2` formed gets hydrolysed to release hydrochloric acid during the reaction. Thus only a small amount of hydrochloric acid is required to initiate the reaction.
