        abstract = {Reaction rate constants for oxidation of 3-alkanones (3-pentanone and 3-hexanone) by nicotiniumdichromate (NDC) were measured at 308 K in aqueous acetic acid medium. The derived order each with respect to NDC and acid was found unity whereas a fractional-order kinetics is exhibited by 3-alkanones. The reaction was proceeded through 2:3 intermediate complex formed between protonated oxidant and enolic ketone in the pre-equilibrium state and subsequently deprotonation of >C-H bond at rate-determining step. The termination of reaction with acrylonitrile does not occur with free radicals. The thermodynamic characteristics of elementary steps of oxidation explaining the obtained results were calculated. The negative activation entropy showed an ordered transition state for reaction. 2,4-DNP derivative and nmr analysis revealed the products of the reaction to be 2,3-diones.},
