Given below are two statements: In the light of the above statements, choose the correct answer from the options given below:
- Both statement I and Statement II are true
- Both Statement I and Statement II are false
- Statement I is correct but Statement II is false
- 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.
Answer: (1)
