Question
A carbonyl compound reacts with hydrogen cyanide to form cyanohydrin which on hydrolysis forms a racemic mixture of a ฮฑ-hydroxy acid. The carbonyl compound is
Answer: A
๐ก Solution & Explanation
The carbonyl compound will be acetaldehyde, so when the acetaldehyde reacts with hydrogen cyanide, then there is formation of cyanohydrin, (ํถํป3ํถํป(ํํป)(ํถํ)) and when it is hydrolyzed the cyanide group will convert into carboxylic group ํถํป3ํถํป(ํํป)(ํถํํํป). So, in this product the carbon atom is joined to all different compounds, hence it will give racemic mixture of alpha-hydroxy acid.
