The method by which aniline cannot be prepared is
- A nitration of benzene followed by reduction with \(\mathrm{Sn}\) and conc. \(\mathrm{HCl}\)
- B degradation of benzamide with bromine in alkaline solution
- C reduction of nitrobenzene with \(\mathrm{H}_{2} / \mathrm{Pd}\) is ethanol
- D potassium salt of phthalimide treated with chlorobenzene followed by the hydrolysis with aqueous \(\mathrm{NaOH}\) solution
Answer & Solution
Correct Answer
(D) potassium salt of phthalimide treated with chlorobenzene followed by the hydrolysis with aqueous \(\mathrm{NaOH}\) solution
Step-by-step Solution
Detailed explanation
Aryl halides do not undergo nucleophilic substitution with potassium phthalimide under ordinary conditions. Thus, method \((d)\) cannot be used for preparation of aniline.
