Which of the following on oxidation followed by hydrolysis gives pyruv...
Oxidation followed by hydrolysis of acetaldehyde cyanohydrin gives pyruvic acid.
Explanation:
Acetaldehyde cyanohydrin is an organic compound with the chemical formula C3H5NO. It is a cyanohydrin formed by the addition of hydrogen cyanide to acetaldehyde. The oxidation of acetaldehyde cyanohydrin results in the formation of pyruvic acid. Pyruvic acid is an important intermediate in many metabolic pathways.
The oxidation of acetaldehyde cyanohydrin involves the removal of two hydrogen atoms and the addition of an oxygen atom. This results in the formation of a carbonyl group and a carboxyl group. The reaction can be represented as follows:
C3H5NO + O2 → C3H4O3 + NH3
The product formed in the oxidation reaction is a lactone, which upon hydrolysis gives pyruvic acid. The lactone undergoes hydrolysis in the presence of water to yield pyruvic acid. The reaction can be represented as follows:
C3H4O3 + H2O → CH3COCOOH
Therefore, the correct option is A) Acetaldehyde cyanohydrin, as it undergoes oxidation followed by hydrolysis to give pyruvic acid.

Acetaldehyde with HCN gives acetaldehyde cyanohydrin
CH3CHO+HCN⟶CH3CH(CN)−OH
on oxidation it gives,
CH3CH(CN)−OH⟶CH3CH(OH)−COOH
CH3CH(OH)−COOH⟶CH3C(COOH)=O
gives pyruvic acid.
CH3CHO+HCN⟶CH3CH(CN)−OH
on oxidation it gives,
CH3CH(CN)−OH⟶CH3CH(OH)−COOH
CH3CH(OH)−COOH⟶CH3C(COOH)=O
gives pyruvic acid.
