The reaction $\mathrm{CH}_{3} \mathrm{COCH}_{3}+4 \mathrm{H} \underset{\text { conc. } \mathrm{HCl}}{\stackrel{\mathrm{Zn}-\mathrm{Hg}}{\longrightarrow}} \mathrm{C}_{3} \mathrm{H}_{8}+\mathrm{H}_{2} \mathrm{O}$ is known as
  1. Rosenmund's reduction
  2. Clemmensen reduction
  3. Wurtz reaction
  4. Kolbe's reaction

Solution

This reaction is known as Clemmensen reduction.
In this reaction, $\mathrm{C}=\mathrm{O}$ group is reduced to $\mathrm{CH}_{2}$ group.
This reaction is useful for carbonyl compounds which are sensitive to base.
