Acetone

Definition and meaning of Acetone in chemistry.

Acetone is a colorless, volatile liquid that is the simplest ketone, with the formula CH3COCH3 (C3H6O). It is widely used as a solvent. Its IUPAC name is propanone.

In more detail

In acetone, a central carbonyl group (C=O) is bonded to two methyl groups, which defines it as a ketone. It mixes completely with water and with most organic solvents, boils at about 56 °C, and is highly flammable. These properties make it a common laboratory and industrial solvent and the basis of many nail-polish removers.
