Given below are two statements:
| Assertion (A): | Experimental reaction of \(\mathrm{CH_3Cl}\) with aniline and anhydrous \(\mathrm{AlCl_3}\) does not give \(o \text { and p-methylaniline. }\) |
| Reason (R): | The \(\mathrm{-NH_2}\) group of aniline becomes deactivating because of salt formation with anhydrous \(\mathrm{AlCl_3}\) and hence yields m-methyl aniline as the product. |
| 1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
| 3. | (A) is True but (R) is False. |
| 4. | (A) is False but (R) is True. |
