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

A

`C_(6)H_(5)CONH_(2)`

B

`CH_(3)CONH_(2)`

C

`CH_(3)CH_(2)CONH_(2)`

D

`CH_(3)CONHCH_(3)`

Text Solution

Verified by Experts

The correct Answer is:
D
Hoffmann bromamide reaction is `R- overset(overset(O)(||))(C)- NH_(2) + Br_(2) + 4KOH overset(Delta)rarr underset("Primary amine")(RNH_(2)) + K_(2)CO_(3) + 2KBr + 2H_(2)O`
This reaction is given by primary amide only. Option (d) `CH_(3)CONHCH_(3)` is a secondary amide, so it will not undergo Hoffmann bromamide reaction
