Question

Which from following compounds is obtained when propionamide is treated with \(\text{Br}_2\) and concentrated aqueous KOH solution ?

• A. \(\text{CH}_3\text{CH}_2\text{CH}_2\text{COOH}\)
• B. \(\text{CH}_3\text{COCH}_3\)
• C. \(\text{CH}_3\text{CH}_2\text{NH}_2\)
• D. \(\text{CH}_3\text{CH}_2\text{Br}\)

Hint:

Hofmann degradation removes one carbon atom as carbonate and gives a primary amine.

Answer 1

The Correct Option is C

Step 1: Rule:
Amide with n carbons gives amine with n - 1 carbons.

Step 2: Apply:
Propionamide (3 C) gives ethylamine (2 C).

Step 3: Answer:
Option (C).

Final Answer:
Option (C). \[ \boxed{\text{(C) } \text{CH}_3\text{CH}_2\text{NH}_2} \]
