Hydrogen Bonding -
It is an electrostatic attractive force between hydrogen of one molecule or part of an molecule and an electronegative atom ( F, O, N ) of another molecule (intermolecular ) or another part of same molecule ( intramolecule )
More electronegative element with small size forms H- bonds. So F, O and N forms H- bonds, Cl does not.
