Method by which aniline cannot be prepared is:

A

reduction of nitrobenzene with `H_(2) // Pd` in ethanol.

B

potassium salt of phthalimide treated with chlorobenzene followed by hydrolysis with aqueous NaOH solution.

C

hydrolysis of phenylisocyanide with acidic solution.

D

degradation of benzamide with bromine in alkaline solution.

Text Solution

Verified by Experts

The correct Answer is:
B

Chlorobenzene does not react with potassium phthalimide because aryl halides are less reactive towards nucleophilie substitution reaction.
