WebDipole moment is used in determining the polarity of molecules. In some molecules, all the bonds will be polar, but when the dipole moment is measured the net polarity of the molecules becomes zero. In the case of CF 4, each C-F bond is polar, but the net dipole moment becomes zero. Dipole moment assists in finding the shape of the molecule.
