Which of the following amides will not undergo Hofmann bromamide reaction?

A

`CH_3CONH_2`

B

`CH_3CONHCH_3`

C

`C_6H_5CONH_2`

D

`CH_3CH_2CONH_2`

Text Solution

Verified by Experts

The correct Answer is:
B
Hofmann bromamide reaction is `R-oversetoversetO(||)C-NH_2+Br_2 + 4KOH oversetDeltato underset"Primary amine"(R NH_2) + K_2CO_3 + 2KBr + 2H_2O`
This reaction is given by primary amide only. Option (b) `CH_3CONHCH_3` is a secondary amide, so it will not undergo Hofmann bromamide reaction.
