Clemensen’s reduction of ketones is carried out in
A.H2 with Pd catalyst
B.Glycol with KOH
C.LiAlH4 in water
D.Zn–Hg with HCl✓ Correct
Explanation
Clemmensen’s reduction is a common reaction which includes reduction of carbonyl compounds. Here, zinc amalgam (which is nothing but a binary solution i.e. liquid in solid solution of zinc and mercury) along with concentrated hydrochloric acid is used for the reduction of ketones to give the corresponding hydrocarbon. Therefore, the correct answer is option (d) Zn–Hg with HCl.
