D - ( + ) - Glyceraldehyde → _ ii ) H _ 2 O / H ^ + _ iii ) HNO _ 3 ^ i ) HCN The products formed in the above reaction

Options

  1. A

    One optically active and one meso product

  2. BTwo optically inactive products
  3. C

    Two optically active products

  4. D

    One optically inactive and one meso product

Correct answer

A.

One optically active and one meso product

Step-by-step solution

The aldehyde group of glyceraldehyde reacts with hydrogen cyanide give cyanohydrin. Two isomers formed in the above step, because aldehyde is planar and changed to tetrahedral centre. On hydrolysis cyanide group convert to carboxylic acid. Upon reaction with nitric acid, the primary alcoholic group undergo oxidation to carboxylic acid group. One compound is meso compound, optically inactive and other compound is optically active.
