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.
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.

Wikipedia
In chemistry, a ketone (alkanone) is an organic compound with the structure RC(=O)R', where R and R' can be a variety of carbon-containing substituents. Ketones and aldehydes are simple compounds that contain a carbonyl group (a carbon-oxygen double bond). They are considered "simple" because they do not have reactive groups like − OH or − Cl attached directly to the carbon atom in the carbonyl group, as in carboxylic acids containing − COOH. Many ketones are known and many are of great importance in industry and in biology. Examples include many sugars ( ketoses) and the industrial solvent acetone, which is the smallest ketone.

The odorous constituent of oil of Orris is a liquid ketone named Irone, to which the violet-like odour is due (though it is not absolutely identical with oil of Violets obtained from the natural flower), and it is the presence of this principle in the rhizome that has long led to the employment of powdered Orris root in the preparation of Violet powders, which owe very little of their scent to the real Violet perfume.
