Abstract

Chalcones can be easily oxidized in presence of oxalic acid, by Cr(VI) in acetic acid medium, the rate of cooxidation was found to be a fractional order with respect to the chalcones and its substituents. The order with respect to the chromic acid is unity whereas order with respect to oxalic acid is also a fractional order. The effect of various parameters such as [H+], [NaCl], [NaNO3] and dielectric constant of the medium by changing the (v/v) ratio of acetic acid and water content were studied .The intermediate is formed between chalcones and a chromic acid
