Abstract

Application of Hammett equation to structure-reactivity correlations of a “localized reaction site” in elucidating the reaction mechanisms of several organic reactions is a very well-knownphenomenon in physical-organic chemistry class-room of senior undergraduate and graduate level students. This is a testament of purely chemical phenomena. There were twosuccessful reports in literature on the application of linear and non-linearHammett equation to claim to be physical property of solubilities of benzoic acids. In this article we tried to apply the same to the dipole moments and melting points of some benzoic acidsand however premature andunsolved.
