MCQ
Note: In the following question a statement of assertion followed by a statement of reason is given. Choose the correct answer out of the following choices.
Assertion: Only a small amount of $\text{HCl}$ is required in the reduction of nitro compounds with iron scrap and $\text{HCl}$ in the presence of steam.
Reason: $\ce{FeCl_2}$ formed gets hydrolysed to release $\text{HCl}$ during the reaction.
  • A
    Both assertion and reason are wrong.
  • B
    Both assertion and reason are correct statements but reason is not correct explanation of assertion.
  • C
    Assertion is correct statement but reason is wrong statement.
  • ✓
    Both assertion and reason are correct statements and reason is correct explanation of assertion.
✓

Answer

Correct option: D.
Both assertion and reason are correct statements and reason is correct explanation of assertion.
$\mathrm{Fe}+2 \mathrm{HCl} \rightarrow \mathrm{FeCl}_2+2[\mathrm{H}]$
Nascent hydrogen reduces nitro compounds. 
$\mathrm{FeCl}_2+\mathrm{H}_2 \mathrm{O}(\mathrm{~g}) \rightarrow \mathrm{FeO}+2 \mathrm{HCl}$
