In general the free energies for the transfer of copper(II) ion from water to the lower alcohols are very positive, ranging from 1.0 in ethylene glycol to 16.5 kcal in t-butyl alcohol. Functions in the dielectric constant fail to account for the influence of the solvent upon the free energy of transfer. However, the linear free energy model of Krygowski and Fawcett for Lewis acid-base interactions provides an adequate correlation between essential variables when the donor basicity is represented by the Kamlet-Taft beta value of the alcohol.
