The method by which aniline cannot be prepared is

Options

  1. Anitration of benzene followed by reduction with Sn and conc. HCl
  2. Bdegradation of benzamide with bromine in alkaline solution
  3. Creduction of nitrobenzene with H ₂ / Pd is ethanol
  4. Dpotassium salt of phthalimide treated with chlorobenzene followed by the hydrolysis with aqueous NaOH solution

Correct answer

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

Step-by-step solution

Aryl halides do not undergo nucleophilic substitution with potassium phthalimide under ordinary conditions. Thus, method (d) cannot be used for preparation of aniline.
