Compound ' (A ) ' undergoes formation of cyanohydrins, which on hydrolysis gives lactic acid ( ( CH ₃ CHOHCOOH ) ). Therefore, compound ' (A ) ' is ____

Options

  1. Aformaldehyde
  2. Bacetaldehyde
  3. Cacetone
  4. Dbenzaldehyde

Correct answer

B. acetaldehyde

Step-by-step solution

Acetaldehyde on reaction with hydrogen cyanide gives cyanohydrin which on hydrolysis gives lactic acid. Therefore compound (A ) is acetaldehyde. Hence, the correct option is (b).
