Cyanide is a chemical compound containing a cyano group (a carbon atom triple-bonded to a nitrogen atom). Cyanide compounds are highly toxic. They bring about asphixiation and kill almost instantly. When cyanide has been used, there is usually the characteristic smell of bitter almonds.

Cyanide compounds[edit | edit source]

  • Hydrogen cyanide, also called prussic acid. A liquid. The fumes of this could be inhaled.
  • Potassium cyanide. A white cystaliine substance which could be added to drinks.
