In acid medium nitrobenzene is reduced to aniline as shown in the reaction
$\mathrm{C}_{6} \mathrm{H}_{5}-\mathrm{NO}_{2}+6[\mathrm{H}] ightarrow \mathrm{C}_{6} \mathrm{H}_{5}-\mathrm{NH}_{2}+2 \mathrm{H}_{2} \mathrm{O}$
The reducing agent used in this reaction is .....
  1. $\mathrm{LiAlH}_{4}$
  2. $\mathrm{Sn} / \mathrm{HCl}$
  3. Na/alcohol
  4. $\mathrm{H}_{2} / \mathrm{Ni}$

Solution

$\mathrm{C}_{6} \mathrm{H}_{5} \mathrm{NO}_{2}+6 \mathrm{H} \stackrel{\mathrm{Sn}+\mathrm{HCl}}{\longrightarrow} \mathrm{C}_{6} \mathrm{H}_{5}-\mathrm{NH}_{2}+2 \mathrm{H}_{2} \mathrm{O}$
