Study on Association of Substituted Benzoic Acids And Other Acids By Physical Methods

Abstract

This paper deals with the preparation of twelve aliphatic and substituted benzoic acids.the structures of these acids are confirmed by some physical methods.The main object of the paper is studying the possibility of association in these acids by physical methods,namely the UV,IR spectra,melting point and distribution methods.The mechanisms of association in these acids in benzene are happen by either hydrogen bonding alone or hydrogen bonding in addition to the ion induce dipole association methods.This depends on the structure of the acid and the temperature of the solution. The idea of ion induce dipole in founded here for the first times as suggested from the collected experimental results. Finally a suitable interpretation is given read any point as support by reference
