- The effect of solvent composition on the rates of some dipole-dipole and ion-dipole reactions has been studied in various pure and mixed solvents like methanol-water, dioxan-water and acetone-water mixtures. There is no simple correlation of the rate constant with the dielectric constant but the rate is related to Grunwald-Winstein 'Y' factor. The parameters of the transition state theory were found to be linearly related to 'Y' values of the solvent composition and the results have been interpreted m the light of Winstein-Fainberg treatment. The decrease in rate constant with increase in polarity of the solvent in case of ion-dipole reaction has been explained in terms of Hughes-Ingold theory.
