The thermodynamic parameters for the solvolysis of the p-nitrobenzyl chloride which take place in the ethanol-water mixture media were determined. From the application of this data to the formula δMΔH≠ = a'Y + bδMΔS≠ the following conclusion was obtained. The substrate constant a' for this reaction was not varied in the media which contain more than 50% alcohol and less than 50% alcohol. From this, it is clear that the mechanism of this reaction is the same both in the water-rich solvent and in the alcohol-rich solvent.
