WebComparing the melting points of benzene and toluene, you can see that the extra methyl group on toluene disrupts the molecule's ability to stack, thus decreasing the cumulative strength of intermolecular London dispersion forces. Note also that the boiling point for toluene is 111 o C, well above the boiling point of benzene (80 o C). The key ...
