WebThe 2-methylbutane has one substituent so it is a little more branched than pentane. This reduces the surface for intermolecular interactions and lowers the boiling point by about 8 o C. The highly branched 2,2-dimethylpropane, on the other hand, lacks this surface interaction and has the lowest boiling point.
