Q. Clemmensen reduction of a ketone is carried out in the presence of which of the following?
A) H₂ and Pt as catalyst
B) Glycol with KOH
C) Zn-Hg with HCl
D) LiAlH₄
Explanation
[Solution from source] Clemmensen reduction converts C=O to CH₂ using zinc amalgam and concentrated HCl. Hydrazine with KOH in ethylene glycol is the Wolff–Kishner reduction, and LiAlH₄ reduces ketones only to alcohols. Answer (3).
