You may find it useful to draw lewis. Substances with high surface tension such as water have very strong intermolecular forces due to hydrogen bonding. 0000005374 00000 n As a result, substances with higher molecular weights have higher London dispersion forces and consequently tend to have higher melting points, boiling points, and enthalpies of vaporization. =L>A(c#|@u|G A general empirical expression for the potential energy between two particles can be written as, \[V(r) = Ar^{-n} + Br^{-m} \label{7.2.1} \]. These substances will also have high viscosity because it is another bulk property related to intermolecular forces of attraction where a higher amount leads to a higher viscosity.
