CHEMISTRY GLOSSARY

Nonpolar molecule is a molecule which has no separation of charge, so no positive or negative poles are formed. For example, the Cl₂ molecule has no polar bonds (molecule with one type of atom), CH₄ is a non-polar molecule (due to its symmetry). Nonpolar molecules do not dissolve in water as they cannot form hydrogen bonds (thus are hydrophobic) but do dissolve in lipids or fats (lipophilic).
