| Abstract The study deals with the tautomerism reaction of type enol keto in benzylidene-o-hydroxyaniline (I), beside the thermodynamic study of such reaction in solution state. The results show the enol content in molecule (I) is predominant as evident from the positive value of average G function of value 4.4 kJ.mole-1. Moreover, others calculated H and S parameters have an average negative values of about -1.1 kJ.mole-1 and -18.0 J.mole-1.K-1 respectively, these support the tautomerism reaction. Finally a comparative study between the tautomerism constant values in solution and gaseous states for the reaction stated above, is given | ||
