Hydrolysis of cyanohydrin derivative produces.A.Carboxylic acidsB.AlcoholsC.AldehydesD.Ketones

To solve the question regarding the hydrolysis of a cyanohydrin derivative, we first need to understand what cyanohydrins are and how they behave during hydrolysis.

Cyanohydrins: Cyanohydrins are organic compounds that contain both a cyano group (-C≡N) and a hydroxyl group (-OH) attached to the same carbon atom. They are typically formed by the reaction of aldehydes or ketones with hydrogen cyanide (HCN).

Hydrolysis of Cyanohydrins: When a cyanohydrin undergoes hydrolysis, it reacts with water, leading to the breakdown of the cyano group. The general reaction can be represented as follows:

The cyanohydrin is treated with water.
The cyano group (-C≡N) is converted into a carboxylic acid (-COOH) group through hydrolysis.
The hydroxyl group (-OH) remains intact.
Resulting Products: The hydrolysis of a cyanohydrin yields:

A carboxylic acid (from the cyano group).
An alcohol (if the original cyanohydrin was derived from an aldehyde, the remaining functional group would be an alcohol).
Given the nature of the hydrolysis and the products formed, the primary product of the hydrolysis of a cyanohydrin derivative is a carboxylic acid.

Answer: A. Carboxylic acids
