Compound ' AA ' undergoes formation of cyanohydrins, which on hydrolysis gives lactic acid (\left(\mathrm{CH}}_{3} \mathrm{CHOHCOOH}\right)). Therefore, compound 'A' is ____Compound ' A ' undergoes formation of cyanohydrins, which on hydrolysis gives lactic acid ((CH _ 3 CHOHCOOH)).

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. Compound ' A ' undergoes formation of cyanohydrins, which on hydrolysis gives lactic acid ((CH _ 3 CHOHCOOH)).
Therefore compound AA is acetaldehyde. Hence, the correct option is (b).
