Select the correct option based on statements below:
| Assertion (A): | Only a small amount of HCI is required in the reduction of nitro compounds with iron scrap and HCI in the presence of steam. |
| Reason (R): | FeCl2 formed gets hydrolyzed to release HCI during the reaction. |
| 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. | Both (A) and (R) are false. |
Hint: Reduction of nitro compounds using metals in acidic medium.
Explanation:
Only a small amount of HCl is used in the reduction of nitro compounds with iron scrap and HCl in the presence of steam. In this reaction, Fe reacts with HCl and form FeCl2, then FeCl2 formed gets hydrolyzed to release HCl during the reaction.
Thus, only a small amount of hydrochloric acid is required to initiate the reaction.
Hence, both assertion and reason are true and the reason is the correct explanation of assertion.
