Q.Nitrobenzene is reduced with granulated $\text{Sn}$ and concentrated $\text{HCl}$. Name the final product and state how this reagent pair compares with $\text{Fe}/\text{HCl}$ in the extent of reduction achieved.

Granulated tin with concentrated hydrochloric acid is another strong metal-acid reducing system, and it carries nitrobenzene fully through to aniline exactly as $\text{Fe}/\text{HCl}$ does: $\text{C}_6\text{H}_5\text{NO}_2 + 6[\text{H}] \xrightarrow{\text{Sn/HCl}} \text{C}_6\text{H}_5\text{NH}_2 + 2\text{H}_2\text{O}$. The two reagent systems are practically interchangeable for this purpose and differ mainly in cost and in the handlin …

Assuming $\text{Sn}/\text{HCl}$ behaves like the milder $\text{Zn}/\text{NH}_4\text{Cl}$ system just because both use a metal …
