Q. No.Given below are two statements:
In the light of the above statements, choose the most appropriate answer from the options given below:
| Statement I: | Benzenediazonium salt is prepared by the reaction of aniline with nitrous acid at \(273-278~ \text{K}.\) It decomposes easily in the dry state |
| Statement II: | Insertion of iodine into the benzene ring is difficult and hence iodobenzene is prepared through the reaction of benzenediazonium salt with \(KI.\) |
In the light of the above statements, choose the most appropriate answer from the options given below:
| 1. | Statement I is correct; Statement II is incorrect |
| 2. | Statement I is incorrect; Statement II is correct |
| 3. | Both Statement I and Statement II are correct |
| 4. | Both Statement I and Statement II are incorrect |
