The main product of the reaction of `CH_3CONH_2` with `Br_2` in aqueous potassium hydroxide medium is

A

`CH_3-CH_2-NH_2`

B

`CH_3Br`

C

`CH_3CONHBr`

D

`CH_3NH_2`

Text Solution

Verified by Experts

The correct Answer is:
D
This is Hofmann's bromamide reaction. In this reaction, product compound has one less C-atom than reactant. So, it causes shortening of C chain.
`R-CONH_2 to R-NH_2`
`CH_3CONH_2 + Br_2 + 4KOH to CH_3NH_2 + 2KBr +2H_2O + K_2CO_3`
