A visual representation of intermolecular forces.
Intermolecular Forces (IMF's) are the forces that hold molecules together. They are not to be confused with the significantly stronger atomic bonds formed by intramolecular forces. The strength of these forces determine the physical properties of substances such as melting point, boiling point, vapor pressure, etc.
The 4 main kinds of IMF's, listed in increasing order, are London Dispersion forces (Van der Waal's Force), Dipole-Dipole, Ionic Forces, and Network Covalent forces. Generally speaking, the stronger the IMF the higher the melting point, boiling point, density, surface tension, and the lower the vapor pressure.
