The effective length of carbon chain (N~E) was calculated by the equation N~E=(PT~S~,~N/PT~B~,~N)·N for the paraffinic hydrocarbon consisting of N carbon atoms, where the PT~S~,~N and PT~B~,~N represent the molecular polarizability index of isomer of straight-chain paraffin and branched-chain paraffin respectively. The result shows that the relationship between the N~E and boiling point Tb(K) of paraffinic hydrocarbons can be expressed by log(1076.575-Tb)=3.034649-5.043171×10^-^2N~E^2^/^3.
