    which is stronger than van der Waal’s or dipole-dipole‚ but weaker than covalent bonding. The effect of hydrogen bonding on intermolecular forces can be demonstrated very well by studying the boiling points of the group 6 hydrides b.p. comparison of main group hydrides Order of priority Hydrogen bonding strongest Dipole -dipole interactions Van der Waals forces Hydrogen bonds result from hydrogen bonded as described above. This results in molecules with hydrogen bonding exhibiting
