cyanohydrins

Chemistry

Organic compounds formed by the addition of hydrogen cyanide to aldehydes or ketones (in the presence of a base). The first step is attack by a CN⁻ ion on the carbonyl carbon atom. The final product is a compound in which a –CN and –OH group are attached to the same carbon atom. For example, ethanal reacts as follows
${CH}_{3} CHO + HCN \to {CH}_{3} CH (OH) (CN)$
The product is 2-hydroxypropanonitrile. Cyanohydrins of this type can be oxidized to α‎-hydroxy carboxylic acids.
