Q.

Given below are two statements:

Statement I: Aniline does not undergo Friedel-Crafts alkylation reaction.

Statement II: Aniline cannot be prepared through Gabriel synthesis.

In the light of the above statements, choose the correct answer from the options given below:

  1. A

    Statement I is correct, but Statement II is false.

  2. B

    Statement I is incorrect, but Statement II is true.

  3. C

    Both Statement I and Statement II are true.

  4. D

    Both Statement I and Statement II are false.

Solution

Aniline's nitrogen lone pair coordinates with AlCl, generating a Lewis acid-base complex that strongly deactivates the ring and blocks Friedel-Crafts alkylation.

Gabriel synthesis uses an SN2 reaction of phthalimide anion with an alkyl halide; aryl halides do not undergo SN2, so aniline cannot be prepared this way.

Both statements are correct.
