Answer:
CH3CHO gives lactic acid on hydrolysis after reacting with HCN.
Explanation:
CH3CHO gives lactic acid on hydrolysis after reacting with HCN.
HCN stands for Hydrogen cyanide.
CH3CHO stands for aldehydes.
Aldehydes cannot be directly used to react with Hydrogen cyanide.
These aldehydes firstly added to sodium or potassium cyanide and then reacted.
