Clemmensen reduction of a ketone is carried out in the presence of which of the following?

Options

  1. AZn - Hg with HCl
  2. BLiAlH ₄
  3. CH ₂ and Pt as catalyst
  4. DGlycol with KOH

Correct answer

A. Zn - Hg with HCl

Step-by-step solution

The reducing agent used in Clemmensen reduction is Zn - Hg and HCl . It converts C = O group into - CH ₂ group. C = O Zn - Hg / HCl CH ₂
