How to tell which molecules have which intermolecular forces?

Inter-molecular? All should...the protons should be attracting the electrons and vise versa.

Ok so hydrogen bonding is the strongest intermolecular force and it only occurs when Hydrogen is bonded with a F, O or N. Such as HF or H2O. There is an attraction because of the partial negative and partial positive side in the molecule in which attracts with the other molecules partial charges. This is the strongest because it includes elements with the most electronegative. 

Dipole-Dipole forces only occur in molecules that are polar. Such as ICl. Since there is partial positive sides and partial negative side in the molecule them there is attraction between other molecule's partial charges. 

London dispersion forces are forces that occur only in molecules that are nonpolar such as CF4 or Cl2. This is the weakest force because there is no attraction between the molecules except for very quick instances when in the molecule there is more electrons on one side of the molecule than the other side.This causes another molecular to also have an imbalance in winch creates an attraction.
