WebReactions with Hydrogen Cyanide The nucleophilic addition reaction between hydrogen cyanide (HCN) and carbonyl compounds (generally aldehydes and ketones) results in the formation of cyanohydrins. Base catalysts are often used to increase the rate of the reaction. WebCyanohydrins are organic compounds having the formula RR′C (OH)CN, where R and R′ can be alkyl or aryl groups. Aldehydes and ketones react with hydrogen cyanide (HCN) in the presence of excess sodium cyanide (NaCN) as a catalyst to field cyanohydrin. These reactions are known as cyanohydrin reactions.

WebThe reaction of aldehydes and ketones with hydrogen cyanide . The facts. Hydrogen cyanide adds across the carbon-oxygen double bond in aldehydes and ketones to produce compounds known as hydroxynitriles. For example, with ethanal (an aldehyde) you get 2-hydroxypropanenitrile: With propanone (a ketone) you get 2-hydroxy-2 … Weband ketone testing, nucleophilic addition with HCN, preparation of aldehydes and ketone, reduction of aldehydes, and ketone.
