When acetamide is treated with `Br_(2)` and caustic soda, then we get

A

N-bromamide

B

bromoacetic acid

C

methanamine

D

ethanamine

Text Solution

Verified by Experts

The correct Answer is:
C
Amides react with bromine and caustic soda to give their corresponding primary amines. Thus, acetamide gives methanamine. This reaction is known as Hofmann's bromamlde degradation reaction.
