Question

$RCONH _{2}$ is converted into $RNH _{2}$ by means of Hofmann bromamide degradation.

In this reaction, $RCONHBr$ is formed from which this reaction has derived its name. Electron donating group at phenyl activates the reaction. Hofmann degradation reaction is an intramolecular reaction.
What are the constituent amines formed when the mixture of (i) and (ii) undergoes Hofmann bromamide degradation?

• A.
• B.
• C.
• D.

Answer 1

Answer: (B)

The amines obtained on Hofmann degradation are as follows:

Amine thus produced is one carbon less than the starting compound.
