Solution

The correct option is C

Explanation for the correct option:

C:

Gabriel Synthesis:

  • By reacting with alkyl halides, potassium phthalimide, a -NH2synthon, enables the creation of primary amines.
  • The phthalimide is no longer a nucleophile and does not react after alkylation.
  • A stable cyclic product is produced when the product is cleaved through a reaction with a base or hydrazine.
  • And only 1o amines can be prepared by Gabriel Synthesis.

Explanation for the incorrect answer:

  • Options A, B and D are not following the Gabriel synthesis.

Therefore, Option C is the correct option.
