| Assertion (A): | In strongly acidic solutions, aniline becomes more reactive towards electrophilic reagents. |
| Reason (R): | The amino group being completely protonated in a strongly acidic solution, the lone pair of electrons on the nitrogen is no longer available for resonance |
| 1. | Both (A) & (R) are True and the reason is the correct explanation of the (A). |
| 2. | Both (A) & (R) are True but the reason is not the correct explanation of the (A). |
