Which of the following reagents is used for the following conversion? CH ₃- CH = CH - CHO CH ₃- CH = CH - CH ₂ OH

Options

  1. AH ₃ O ⁺
  2. BZn - Hg / HCl
  3. CH ₂ / Ni
  4. DLiAlH ₄

Correct answer

D. LiAlH ₄

Step-by-step solution

(C) LiAlH ₄ does not reduces isolated olefin bond and hence it can reduce unsaturated aldehyde and ketones to unsaturated alcohols.
