Vedclass · Answer

(B) In the reduction of nitro compounds using iron scrap and $HCl$, iron reacts with $HCl$ to produce $FeCl_2$ and hydrogen gas. The $FeCl_2$ formed undergoes hydrolysis in the presence of water to produce $Fe_3O_4$ and regenerate $HCl$. This regenerated $HCl$ further reacts with more iron to continue the reduction process. Therefore, only a catalytic amount of $HCl$ is required to initiate the reaction. Both the assertion and the reason are correct, and the reason provides the correct explanation for the assertion.

Assertion: Only a small amount of $HCl$ is required in the reduction of nitro compounds with iron scrap.
Reason: $FeCl_2$ formed gets hydrolysed to release $HCl$ during the reaction.
