Question

Which of the following amines is not obtained by Gabriel phthalimide synthesis?

• A. Aniline
• B. Benzyl amine
• C. Methyl amine
• D. Isobutyl amine

Hint:

Gabriel synthesis needs an alkyl halide for SN2, so aryl amines cannot be made.

Answer 1

The Correct Option is A

Step 1: Idea:
The method needs a suitable alkyl halide that undergoes $\text{S}_\text{N}2$ with the phthalimide anion.

Step 2: Result:
Chlorobenzene would be needed for aniline, and it does not react. The other three halides are primary alkyl or benzyl halides, which react easily.

Final Answer:
Aniline is not obtained by this method, option (A). \[ \boxed{\text{Aniline}} \]
