PHYSICO-CHEMICA L STUDIES ON SOME ORGANIC COMPOUNDS AND ITS COMPlEXES WITH SOME TRANSITION METALS

Abstract

The present thesis comprises three chapters. The first one included the introduction. The second chapter is concerned with the experimental part. The third chapter is devoted to the results and discussions and divided into four parts. Part I Proton-ligand dissociation constants of quinoline azodyes and their substituted derivatives, and metal-ligand stability constants of
