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.
Molecules with mirror symmetry like oxygen, nitrogen, carbon dioxide, and carbon tetrachloride have no permanent dipole moments. Even if there is no permanent dipole moment, it is possible to induce a dipole moment by the application of an external electric field.
