Method by which Aniline cannot be prepared is:

Method by which Aniline cannot be prepared is:
  1. Hydrolysis of phenylisocyanide with acidic solution
  2. Degradation of benzamide with bromine in alkaline solution
  3. Reduction of nitrobenzene with H2/Pd in ethanol.
  4. Potassium salt of phthalimide treated with chlorobenzene followed by hydrolysis with aqueous NaOH solution.

Solution

The method by which aniline cannot be prepared is the method potassium salt of phthalimide treated with chlorobenzene followed by hydrolysis with aqueous NaOH solution.


This is because aryl halides do not undergo nucleophilic substitution with potassium phthalimide under ordinary conditions.


Due to resonance C - Cl bond acquires double bond character.
