What can be the product of Hoffmann bromamide degradation reaction? |
$(CH_3)_2NH$ $(CH_3)3N$ $CH_3NH_2$ $NH_3$ |
$CH_3NH_2$ |
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.
