Method by which Aniline cannot be prepared is:
Options
- AHydrolysis of phenylisocyanide with acidic solution
- BDegradation of benzamide with bromine in alkaline solution
- CReduction of nitrobenzene with H 2 / P d in ethanol.
- DPotassium salt of phthalimide treated with chlorobenzene followed by hydrolysis with aqueous NaOH solution.
Correct answer
D. Potassium salt of phthalimide treated with chlorobenzene followed by hydrolysis with aqueous NaOH solution.
Step-by-step 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.
