These forces are responsible for the attraction between molecules and also for the cohesion of non-polar substances. London dispersion forces weak compared to other intermolecular forces, but they important because they the only intermolecular force that present in all substances. London dispersion forces are caused by the uneven distribution of electrons in the electron clouds of atoms. This uneven distribution creates temporary dipoles, which are responsible for the attractive force between molecules. However london dispersion forces increase with the size of the molecule and with the number of electrons in the molecule.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"London_Dispersion_Forces_Examples\"><\/span>London Dispersion Forces Examples<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The London dispersion forces are weak forces that exist between the electron clouds of adjacent atoms.
