  Ketone \Ke"tone\ (k[=e]"t[=o]n), n. [Cf. {Acetone}.] (Chem.)
     One of a large class of organic substances resembling the
     aldehydes, obtained by the distillation of certain salts of
     organic acids and consisting of carbonyl ({CO}) united with
     two hydrocarbon radicals. In general the ketones are
     colorless volatile liquids having a pungent ethereal odor.


     [1913 Webster]
  
     Note: The ketones are named by adding the suffix-one to the
           stems of the organic acids from which they are
           respectively derived; thus, acetic acid gives acetone;
           butyric acid, butyrone, etc.
           [1913 Webster]
