Question

whats the difference between dipole dipole interaction and london dispersion forces?

Answer 1

Dispersion forces are intermolecular forces that occur in all bonding's between elements.

Dipole-dipole forces occur when the electronegative of on elements is much stronger than the other. You can determine this using a electronegative chart.

Hydrogen bonding only occurs with hydrogen and either Oxygen, Florine and Nitrogen. This is the strongest of the 3 types of bonds.
