MHT CET Chemistry Question (2026) — Solution

Step-by-step solution

Propionamide is CH _3 CH _2 CONH _2. The reaction of an amide with Br _2 and concentrated aqueous KOH is known as the Hoffmann bromamide degradation reaction. In this reaction, the amide is converted into a primary amine with one carbon atom less than the parent amide. CH _3 CH _2 CONH _2 + Br _2 + 4 KOH CH _3 CH _2 NH _2 + K _2 CO _3 + 2 KBr + 2 H _2 O The product obtained is ethylamine ( CH _3 CH _2 NH _2). Answer: CH _3 CH _2 NH _2
