JEE Main Chemistry question
Assertion: In strongly acidic solutions, aniline becomes MORE reactive towards electrophilic reagents.
Reason: The amino group being completely protonated in strongly acidic solution, the lone pair of electrons on nitrogen is no longer available for resonance.
Answer: (D)
Solution
The Assertion is false: in strongly acidic solution, aniline's group is protonated to , which is an electron-withdrawing, meta-directing, DEACTIVATING group, so the ring actually becomes LESS reactive
