The London force is directly related to the polarizabilities of the corresponding molecules.
Consider the following table of molecular polarizability, a:

From these data, come up with a model to account for the contribution of each atom to the polarizability of a molecule. Predict the polarizability of C4H10 and C2H5Cl.
