Acetone is considered a polar molecule because it contains an imbalance of electrons. Acetone shares some properties with nonpolar molecules, such as being water soluble.
Nonpolar bonds are formed when two atoms share an equal number of electrons. Examples of nonpolar bonds include fats and oils. Nonpolar bonds are usually hydrophobic or insoluble in water. Polar bonds are formed from an uneven distribution of electrons.
Acetone is a molecule made carbon, hydrogen and oxygen. It is colorless and highly flammable. It is often used as solvent to dissolve other substances such as paint, fingernail polish and glues. Acetone is toxic if ingested.
