Abstract
THE forces between molecules of organic liquids of non-ionic type are ordinarily of such short range that they act only when the molecules are in contact. The magnitude of the force depends mainly upon the area, and the nature of, the two contacting molecular surfaces. This principle of independent surface action has been a useful guide in the development of theories of surface tension phenomena and should be equally valuable for theories of vapour pressures and solubilities. It leads directly to the concept of molecules having hydrophobic and hydro-philic parts which spread as oriented monolayers on a water surface.
