What type of intermolecular bond forms between the positive and negative ends of two adjoining polar molecules?

A. Non-Polar Covalent

B. Hydrogen

C. Dispersion

D. Dipole to Dipole

Dipole-dipole interactions occur when the partial charges formed within one molecule are attracted to an opposite partial charge in a nearby molecule. Polar molecules align so that the positive end of one molecule interacts with the negative end of another molecule.

So the answer is, D.) dipole to dipole.
