Q. Consider the following reaction: C₆H₅COCl —(H₂, Pd–BaSO₄)→ 'A' The product 'A' is
A) C₆H₅CHO
B) C₆H₅OH
C) C₆H₅COCH₃
D) C₆H₅Cl
Explanation
[Solution from source] This is the Rosenmund reduction: hydrogen over poisoned Pd–BaSO₄ reduces an acid chloride only as far as the aldehyde, so benzoyl chloride gives benzaldehyde, C₆H₅CHO. The poisoned catalyst prevents further reduction to the alcohol. Answer (1).
