Question

Gabriel phthalimide synthesis is used for the preparation of

• A. tertiary amine
• B. acid synthesis
• C. primary amine
• D. secondary amine

Hint:

Gabriel phthalimide synthesis is a method for preparing primary amines from alkyl halides. It avoids the formation of secondary or tertiary amines.

Answer 1

The Correct Option is C

The Gabriel phthalimide synthesis is a reaction used to prepare primary amines. It involves the reaction of phthalimide with an alkyl halide, typically in the presence of a base, followed by hydrolysis to yield a primary amine.
Step 1: Gabriel phthalimide reaction overview.
The reaction begins with the nucleophilic attack of phthalimide on the alkyl halide, leading to the formation of an imidate intermediate. After hydrolysis, this intermediate is converted into the desired primary amine.
Step 2: Evaluate the options.
- Option 1: Tertiary amine: This is not correct as Gabriel phthalimide synthesis does not yield tertiary amines.
- Option 2: Acid synthesis: Gabriel phthalimide synthesis is not used for acid synthesis.
- Option 3: Primary amine: This is the correct answer. The Gabriel phthalimide synthesis specifically prepares primary amines.
- Option 4: Secondary amine: This is incorrect, as secondary amines are not the product of this reaction.
Step 3: Conclusion.
The correct product of Gabriel phthalimide synthesis is primary amines.
Final Answer: \[ \boxed{\text{The correct answer is primary amine.}} \]
