Dipole Moments Molecules whose centers of positive and negative charge do not coincide, have an asymmetric charge distribution, and are polar. These molecules have a dipole moment. The dipole moment has the symbol μ . μ is the product of the distance,d, separating charges of equal magnitude and opposite sign, and the magnitude of the charge, q. Molecules that have a small separation of charge have a small m. Molecules that have a large separation of charge have a large m.

Unformatted text preview: There are some nonpolar molecules that have polar bonds. There are two conditions that must be true for a molecule to be polar. 1. There must be at least one polar bond present or one lone pair of electrons. 2. The polar bonds, if there are more than one, and lone pairs must be arranged so that their dipole moments do not cancel one another....
