Nucleophilic Addition of Hydrogen cyanide to Aldehydes and Ketones

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-methylpropanenitrile: Note: When you are naming these compounds, don''t forget that
