Question

Which from following amines is obtained by Gabrial phthalimide synthesis?

• A. \(\text{C}_6\text{H}_5\text{NH}_2\)
• B. \(\text{C}_2\text{H}_5\text{NH}_2\)
• C. \((\text{CH}_3)_2\text{NH}\)
• D. \(\text{C}_2\text{H}_5\text{N}(\text{CH}_3)_2\)

Hint:

Gabriel synthesis gives only primary aliphatic amines.

Answer 1

The Correct Option is B

Step 1: Rule:
Gabriel synthesis: primary aliphatic amines only.

Step 2: Eliminate:
Aniline is aromatic, dimethylamine is secondary, and the last option is tertiary.

Step 3: Answer:
Ethylamine, option (B).

Final Answer:
Option (B). \[ \boxed{\text{(B) } \text{C}_2\text{H}_5\text{NH}_2} \]
