Dispersion Forces
• All molecules experience these forces.
• At any given instant there may be more electrons at
one end of a molecule than at the other, giving a short-
lived polarity.
• A nonpolar particle (helium atoms below) can be
temporarily polarized to create dispersion force.
• The tendency of an electron cloud to distort is
called its polarizability.
