In the given transformation, which of the following is the most appropriate reagent?

Options

  1. ANH ₂ NH ₂, (-) OH
  2. BZn - Hg / HCl
  3. CNa , Liq. NH ₃
  4. DNaBH ₄

Correct answer

A. NH ₂ NH ₂, (-) OH

Step-by-step solution

ZnHg / HCl can't be used due to the presence of acid sensitive group i.e. OH and Na / Liq . NH ₃ and NaBH ₄ convert - CO - into - CH ( OH )-
