Aniline does not undergo
- A nitration
- B sulphonation
- C Friedel-Craft's-reaction
- D bromination
Answer & Solution
Correct Answer
(C) Friedel-Craft's-reaction
Step-by-step Solution
Detailed explanation
Aniline does not undergoes Friedel-Craft's
reaction due to the presence of an amino \(\left(-\mathrm{NH}_2\right)\) group attached to the aromatic ring. This amino group makes the aromatic ring highly nucleophilic and deactivates the ring towards electrophilic attack due to the electron donating nature of the lone pair on nitrogen.
