Cyanohydrin reactions occurs when an aldehyde or ketone gets treated by a cyanide anion (such as HCN) or a nitrile forming a cyanohydrin product. This special reaction is a nucleophilic addition, where the nucleophilic CN-attacks the electrophilic carbonyl carbon on the ketone, following a protonation by HCN, thereby the cyanide …

Cyanocarbons are organic compounds bearing enough cyano functional groups to significantly alter their chemical properties. Illustrative cyanocarbons: • Tetracyanoethylene, which reduces to a stable anion, unlike most derivatives of ethylene. • Pentacyanocyclopentadiene, which forms an air-stable anion, in contrast to cyclopentadiene.
