Rosenmund reduction is used for the preparation of
  1. carboxylic acid
  2. aldehydes
  3. esters
  4. alcohols

Solution

Rosenmund reduction is used for the preparation of aldehydes. In this reaction, the aldehyde group is obtained by the reduction of an acid chloride using hydrogen in the presence of Lindlar's catalyst.
\(\mathrm{RCOCl}+\mathrm{H}_{2}\)\(\stackrel{\text {Lindlar scatalyst}}{\longrightarrow} \mathrm{RCH} \mathrm{O}+\mathrm{HCl}\)
