The objective of this paper is to the kinetic study of oxidation of Benzon in acidic medium by Ce. (IV). Effect of variation in Concentration of Benzoin, Ce (IV), HClO4, % Acetic acid, temperature variation etc. were studied. Product study was carried out by the suggesting a free radical mechanism. Reaction was of consecutive type and products formed proceed through stable intermediate Benzil. Increase in dielectric constant decrease the rate of reaction. Oxidation of Benzoin proceeds through formation of stable intermediate and thus oxidation studies of these intermediates can also be carried out.
