Select the correct option based on statements below:
| Assertion (A): | N-Ethylbenzene sulphonamide is soluble in alkali. |
| Reason (R): | The hydrogen attached to nitrogen in sulphonamide is strongly acidic. |
| 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. |
Hint: Primary amines form soluble compounds with benzene sulphonyl chloride.
Explanation:
The structure of N-ethylbenzene sulphonamide is as follows:
N-ethylbenzene is soluble in alkali because hydrogen attached to nitrogen in sulphonamide is strongly acidic and forms a salt during the reaction.
The reaction is as follows:
Thus, option 1 is the correct answer.
