Claim: Cyanohydrin is generated as an intermediate in the industrial production of methyl methacrylate and In the laboratory, serves as a source of HCN.
Evidence: A cyanohydrin reaction is an organic chemical reaction by an aldehyde or ketone with a cyanide anion or a nitrile to form a cyanohydrin. With HCN in acidic conditions – i.e. the cyanohydrin is the functional group CN–C–OH. Cyanohydrins can be formed by the cyanohydrin reaction, which involves treating a ketone or an aldehyde with hydrogen cyanide (HCN) in the presence of excess amounts of sodium cyanide (NaCN) as a catalyst:
