It's important to note here that in order for a solution to form, the molecules must be either both polar or both non-polar ... WebThe dipole moment of a molecule is therefore the vector sum of the dipole moments of the individual bonds in the molecule. If the individual bond dipole moments cancel one another, there is no net dipole moment. Such is the case for CO 2, a linear molecule (part (a) in Figure 2.2.8). Each C–O bond in CO 2 is polar, yet experiments show that ...
