The factors affecting on association of some carboxylic acids effect of solvent, isomerism, conjugation process and steric effect

Abstract EN

The study is mainly concerned with the physical factors affecting on association of carboxylic acids such as type of solvent, isomers, conjugation and steric effect of acid.

The degree of association of carboxylic acid is depend on the type of cis or trans isomer of acid.

It is also increased by either increasing the number of conjugated double bonds or by introducing a polar group, taking into consideration a planer structure of acid.

Cis isomers of carboxylic acids prevent the association process by formation of acid monomers, while trans isomers facilitate the formation of dimers or polymers.

Finally exchange of solvent from non polar (benzene) to polar (nitrobenzene), prevents the association process by formation of monomers.
