Molecular attraction

Molecular attraction occurs when neutrally-charged molecules nevertheless experience the uneven distribution of electrons over their structure due to London Forces induced by random variations of electron density occurring in non-polar compounds, hydrogen bonding due to the production of what is essentially a bare proton when it is bonded with a strongly electronegative element such as fluorine, oxygen or nitrogen, and the dipole-dipole interaction between compounds that are polar, such as salt. The properties of liquids and the expansion of water ice when it freezes are due to molecular attraction.
