Cyanohydrins when reacted with mineral acid produces _?
Correct answer: B. Alpha hydroxy carboxylic acids
- A. Beta Hydroxy carboxylic acids
- B. Alpha hydroxy carboxylic acids
- C. Carboxylic acids
- D. Unsaturated acids
Explanation
Hydrolysis of cyanohydrin derivative produces carboxylic acids. Cyanohydrin derivatives are obtained by addition of a molecule of HCN to C=O double bond of aldehdyes or ketones. Since the OH group is attached to the alpha carbon in the final product, it is called alpha hydroxy carboxylic 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.
