ketone

Any of a class of organic compounds, such as acetone, characterized by having a carbonyl group in which the carbon atom is bonded to two other hydrocarbon groups and having the general formula R(CO)R″, where R may be the same as R″.

A compound in which the carbonyl group CO unites two alcohol radicals: as, methyl-ethyl ketone, CH₃.CO.C₂H₅.

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.

A homologous series of organic molecules whose functional group is an oxygen atom joined to a carbon atom—by a double bond—in a carbon-hydrogen based molecule.
