Question:
Which of the following is obtained by Rosenmund's reduction of acyl chloride?
Which of the following is obtained by Rosenmund's reduction of acyl chloride?
Show Hint
Rosenmund’s reduction selectively converts acyl chlorides to aldehydes without over-reduction.
Updated On: Mar 6, 2025
- Aldehyde
- Alcohol
- Hydrocarbon
- Alkyl chloride
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Reaction Mechanism:
Rosenmund's reduction involves catalytic hydrogenation of acyl chlorides to aldehydes. \[ RCOCl + H_2 \xrightarrow{Pd/BaSO_4} RCHO + HCl \] Step 2: Why aldehyde?
- The catalyst palladium on barium sulfate prevents over-reduction to alcohol.
