What causes dipole interactions

A dipole-dipole refers to an intermolecular force, which takes place in between the two molecules that are polar. They take place when the slight negative terminal of one polar molecule gets fascinated towards the slight positive terminal of another polar molecule. These are weaker bonds in comparison to hydrogen bonds, however, they are stronger in comparison to London dispersion forces.

Dipole-Dipole interactions result when two dipolar molecules interact with each other through space. When this occurs, the partially negative portion of one of the polar molecules is attracted to the partially positive portion of the second polar molecule
