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

  1. Both statement I and Statement II are true
  2. Both Statement I and Statement II are false
  3. Statement I is correct but Statement II is false
  4. Statement I is incorrect but Statement II is true

Answer

(1) Both statement I and Statement II are true

Solution

Statement I: Aniline is a Lewis base and forms a salt with the Lewis acid AlCl3; the N acquires a positive charge, which deactivates the ring. So aniline does not undergo Friedel-Crafts reaction. True.

Statement II: Gabriel synthesis needs SN2 attack of phthalimide anion on an alkyl halide; aryl halides do not undergo this nucleophilic substitution, so aromatic primary amines (aniline) cannot be prepared by it. True.
