Web3. If the molecule contains a hydrogen atom bonded to a highly electronegative atom AND contains a fluorine, oxygen, or nitrogen atom that has a lone pair of electrons, hydrogen bonding (a special class of dipole-dipole forces) will exist in the substance. Hydrogen bonds are typically stronger than other dipole-dipole forces.
