What can be the product of Hoffmann bromamide degradation reaction?

The correct answer is Option (3) → $CH_3NH_2$

Core Concept

Hoffmann bromamide degradation converts an amide into a primary amine with one carbon less.

General reaction:

RCONH₂ → RNH₂

Explanation

Option 1: (CH₃)₂NH

This is a secondary amine. Hoffmann degradation always gives primary amines, not secondary.

Option 2: (CH₃)₃N

This is a tertiary amine. Such amines are not formed in Hoffmann reaction.

Option 3: CH₃NH₂

If acetamide (CH₃CONH₂) undergoes Hoffmann degradation, it forms methylamine (CH₃NH₂). Thus, this is a correct product.

Option 4: NH₃

Ammonia is not formed directly in this reaction unless the starting compound is formamide.
