Abstract:From a comparison of the pKa values of various compounds in the solvent 1,2-dichloroethane, m-cresol, acetic acid and pyridine, the differences in basicity of these solvents could be determined. If the basicity of 1,2-dichloroethane is taken as 0 pK units, the basicities of m-cresol, acetic acid and pyridine were found to be 3, 7 and 11 pK units, respectively. It is shown how these differences in basicity can serve to predict pKa values in solvents belonging to the Brønsted classes 5–8.
