ketone
n 1: any of a class of organic compounds having a carbonyl group
linked to a carbon atom in each of two hydrocarbon radicals

The Collaborative International Dictionary of English v.0.48 (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.
[1913 Webster]
