WebIn polyatomic molecules, each bond has an individual bond moment. The dipole moment (μ) of a molecule is the vectorial addition of such bond moments. In the cases where all the individual bond moments are zero (homoatomic molecules), the resultant dipole moment is always zero. However, the converse is not true. WebTherefore, in polyatomic molecules (i.e., molecules made up of three or more atoms), the net dipole moment is the vector sum of all bond dipole moments present in the molecule.
