The dipole moment of a molecule is therefore the vector sum of the dipole moments of the individual bonds in the molecule. Q: Examine his results carefully and check the box next to the incorrect quantity in each row if any. Justify your answer. While in chloromethane H atoms won't face much repulsion from each other rather they would feel more repulsion from cl, hence they will be closer and increase the net dipole. 10-066: Comparing Dipole Moments If the individual bond dipole moments cancel one another, there is no net dipole moment. The molecular dipole moment can be represented as the sum of the individual atomic dipole moments and the pairwise atomic dipole contributions.
