What is the definition of a H-Bond?
A H-bond is an attraction between molecules. It is therefore an intermolecular force, and in fact one of the strongest. Molecules which exhibit H-bonding must contain a hydrogen that is directly bonded to a N, O or F containing a lone pair of electrons. This is due to the strong polarity of the bond (as N, O and F are all highly electronegative).
