Explain how dipole interactions and dispersion forces are related. first, explain what produces the attractions between polar molecules. then, explain what produces dispersion forces between molecules. which intermolecular force is stronger?

One end of the polar molecule is slightly negative and the other end is slightly positive and that's what produces the attraction between the polar molecules. The weakest of all molecular interactions are caused by the motion of electrons and that is what produces dispersion between molecules

Must be negative.substance increases

The answer is c - the principal of original lateral continuity.
