aligned CH ₂= CH - CHO ? CH ₂= & CH & - CH ₂- OH aligned Suitable reagent for conversion of following reaction?

Options

  1. ANaBH ₄
  2. BNi / H ₂
  3. CZn / Hg / HCl
  4. DRed P + Hi

Correct answer

A. NaBH ₄

Step-by-step solution

The suitable reagent for the conversion CH ₂= CH - CHO ? CH ₂= CH - CH ₂- OH is NaBH ₄ . It is a selective reagent and does not reduce carbon-carbon double bond. Thus, unsaturated alcohols can be prepared.
