Comparison for these substances in terms

1/6/2007The alkane (propane) will have the weakest intermolecular forces (only van der waals) and will thus have the lowest boiling point I think that dipole-dipole forces can contribute something moreso in the alcohols than in the alkane but hydrogen bonding is stronger boiling points: propane isopropanol propylene glycol glycerol
