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.
Dipole-dipole attractions. In addition to the attractive London dispersion forces, we now have a situation where the molecule is polar. We say that the molecule has a permanent dipole. Now, the molecules line up.The positive ends end up near to another molecule's negative end: Since this dipole is permanent, the attraction is stronger.However, we only see this sort of attraction between molecules that are polar. It is usually referred to as dipole-dipole interaction.n addition to the attractive London dispersion forces, we now have a situation where the molecule is polar.
