The oxidation is first order each in [substrate] and the [oxidant]. The reaction follows an acid catalysed path, exhibiting second order dependence in [H+]. Bunnett's plot indicates that water acts as a nucleophile. Protonated form of oxidant has been postulated as the reacting oxidizing species. The rate studied at four different temperatures enabled us to calculate activation parameters. A suitable mechanism has been proposed.
