The kinetics of oxidation of benzaldehyde by potassium bromate in an acetic acid medium have been studied.The reaction is first order with respect to oxidant concentration whereas the order with respect to substrate is less than one.Hydrogen ion accelerates the rate of reaction.A mechanism involving the formation of an unsamble bromate ester which decomposes to the reaction products has been suggested.The activation parameters associated with the rate-determining step and the thermodynamic values associated with the equilibrium stage have been computed.The effects of various functional groups on the ring at the ortho, meta, and para positions of benzaldehyde have also been examined.
