Question:
Which one of the following can be prepared by Gabriel phthalimide synthesis?
Which one of the following can be prepared by Gabriel phthalimide synthesis?
Show Hint
Gabriel phthalimide synthesis prepares primary aliphatic amines, not aniline or other aromatic amines.
Updated On: Apr 29, 2026
- 2-Aminotoluene
- Aniline
- 4-Bromoaniline
- Allylamine
- N-Methylethanamine
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Concept:
Gabriel phthalimide synthesis is used to prepare primary aliphatic amines. It does not give aromatic amines.
Step 1: Identify product type.
The method is suitable for: \[ \text{Primary aliphatic amines} \]
Step 2: Check options.
Allylamine is a primary aliphatic amine: \[ CH_2=CH-CH_2NH_2 \]
Step 3: Conclusion.
Hence, allylamine can be prepared by Gabriel phthalimide synthesis.
