Cyanohydrins, when reacted with mineral acid, produce _.
Correct answer: B. Alpha hydroxy carboxylic acid
- A. Beta hydroxy carboxylic acid
- B. Alpha hydroxy carboxylic acid
- C. Carboxylic acid
- D. Unsaturated acid
Explanation
The hydrolysis of cyanohydrin gives alpha hydroxy. carboxylic acids. In the above reaction, the cyano group is hydrolyzed to a carboxylic acid functional group. The number of carbon atoms in the alpha hydroxy carboxylic acid is the same as the number of carbon atoms in the cyanohydrin e.g. The hydrolysis of acetaldehyde cyanohydrin gives lactic acid.

About Aldehydes and Ketones
Aldehydes and ketones contain the polar carbonyl group, but aldehydes are generally more readily oxidised and more reactive than ketones. Coverage includes preparation by oxidation or reduction routes, nucleophilic addition of reagents such as hydrogen cyanide and bisulfite, and tests that distinguish aldehydes from ketones.
