Question

Compound A undergoes formation of cyano- hydrin which on hydrolysis gives lactic acid (.CH3CH(.OH.)COOH.) . Therefore, compound A is (A) Acetaldehyde (B) Acetone (C) Benzaldehyde (D) Formaldehyde

Tardigrade Admin · Accepted Answer

Acetaldehyde on reaction with HCN forms acetaldehyde cyanohydrin which upon acid catalysed hydrolysis forms an α - hydroxyl acid i.e. lactic acid. <img class="img-fluid question-image" alt="Solution" src="https://cdn.tardigrade.in/q/nta/c-ocp4lthkch18.png" />

Q. Compound A undergoes formation of cyano- hydrin which on hydrolysis gives lactic acid $(C H_{3} C H (O H) COO H)$ . Therefore, compound A is

Acetaldehyde

Acetone

Benzaldehyde

Formaldehyde

Acetaldehyde on reaction with HCN forms acetaldehyde cyanohydrin which upon acid catalysed hydrolysis forms an $α$ - hydroxyl acid i.e. lactic acid.
