KETONE
Ke"tone, n. Etym: [Cf. Acetone.] (Chem.)
Definition: 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.
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.
