The dipole moment of a molecule can be predicted by looking at the molecule's structure and the location of the dipoles within the molecule. When a molecule has no dipole moment, it will be nonpolar. A molecule with a dipole moment will be polar.
A molecule is nonpolar if: There are also two cases in which you can be certain that a molecule is nonpolar. The first is the trivial case in which a diatomic molecule consists of only one kind of atom. Larger molecules, even if they have only one kind of atom, are sometimes polar. This will occur when the central atom has one or more pairs of nonbonded electrons. One example of this is ozone, O 3. The middle oxygen atom has a lone pair of electrons and this lone pair gives the molecule its polarity.
