are stronger intermolecular forces than Dispersion forces
occur between molecules that have permanent net dipoles (polar molecules), for example, dipole-dipole interactions occur between SCl2 molecules, PCl3 molecules and CH3Cl molecules. If the permanent net dipole within the polar molecules results from a covalent bond between a hydrogen atom and either fluorine, oxygen or nitrogen, the resulting intermolecular force is referred to as Hydrogen Bonding.
The partial positive charge on one molecule is electrostatically attracted to the partial negative charge on a neighboring molecule.
