Making Connections: Chemistry Assignment By. Sujay Sukumar 5. a) When analyzing the graph‚ a relationship between the hydrocarbon chain of the alkane and its corresponding boiling point can certainly be noticed. There is a increasing correlation which can be explained using the theory that as each hydrocarbon chain gets bigger‚ there are more atoms and thus more electrons which contributes to higher dispersion forces and therefore a higher boiling point which is clearly seen through the graph.
