Ketone
(gcide) | 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.
