Dipole-Dipole Interaction

This causes the electron on the total heat atom to be strongly attracted to the oxygen, leaving a super localized positive charge on the hydrogen atom, and a highly localized negative charge on the oxygen atom. AS a result, the electrostatic attraction between these molecules entrust be greater than for polar molecules that do not take on hydrogen covalently bonded to oxygen, fluorine, or nitrogen.

Melting and boiling points result from reformist weakening of the attractive forces between covalent molecules, so the stronger the intermolecular force that exists, the more than energy it will take to black market the solid or boil the liquid (Intermolecular, 2004). If only spreading forces are present, such as in carbon dioxide, the more electrons the molecule has (and so the more mass), the stronger the dispersion forces will be, so the higher the melting and boiling points will be. Carbon dioxide (mass 44) has a boiling point of -79C.
