| nitrile | <chemistry> Any one of a series of cyanogen compounds; particularly, one of those cyanides of alcohol radicals which, by boiling with acids or alkalies, produce a carboxyl acid, with the elimination of the nitrogen as ammonia. The nitriles are named with reference to the acids produced by their decomposition, thus, hydrocyanic acid is formic nitrile, and methyl cyanide is acetic nitrile. See: Nitro-.
