Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Recall reaction.
Rosenmund reduction is catalytic hydrogenation of acid chlorides (R–COCl) using Pd/BaSO$_4$ poisoned catalyst.
Step 2: Write reaction.
R–COCl + H$_2$ $\xrightarrow{Pd/BaSO_4}$ R–CHO (aldehyde).
Step 3: Conclude.
The product is always aldehyde. Final Answer: \[ \boxed{Aldehyde} \] % Quciktip
