Question

Which one of the following reactions is Rosenmund's reaction?

• A. Aldehydes are reduced to alcohols
• B. Acids are converted to acid chlorides
• C. Alcohols are reduced to hydrocarbons
• D. Acid chlorides are reduced to aldehydes in the presence of $H_2,Pd-BaS{O}_4$

Answer 1

The correct option is D Acid chlorides are reduced to aldehydes in the presence of $H_2,Pd-BaS{O}_4$

When benzoyl chloride reacts with $H_2$ in the presence of $Pd-BaS{O}_4$, benzaldehyde will be formed. This reaction is known as Rosenmund's reaction.
