Cyanide - Wikipedia

A cyanide is a chemical compound that contains the group C≡N. This group, known as the cyano group, consists of a carbon atom triple-bonded to a nitrogen atom. In inorganic cyanides, the cyanide group is present as the anion CN−. . Oral ingestion of a small quantity of solid cyanide or a cyanide solution as little as 200
