Oxidative properties of Cr(VI) are of considerable importance in both analysis and oxidation of organic and inorganic substrates 1,2,3. Cr (VI) in water exists as CrO 4 2-, HCr 2 O 7 2and H 2 Cr 2 O 7 2,4. Of all these species, HCrO 4 has been identified as the only active oxidizing species in aqueous acidic solution 1,2,5,6,7. Although some kinetic information has been published on the oxidation of secondary alcohol by Cr(VI) 1,2, 8-16 complementary studies on its possible reaction pathways are scanty. It is in the light of this that the present work was undertaken with the aim of providing relevant information on the plausible mechanism for the electron transfer reaction of 2-methylpentane-2,4-diol. EXPERIMENTAL Materials 2-methylpentane-2,4-diol (BDH) hereafter referred to as diol was used as supplied in making its standard solution. Sodium dichromate solution in distilled water was then standardized using titrimetric method 17. A stock solution of HCl was prepared by diluting the commercial acid (M&B) and the solution was standardized titrimetrically using sodium carbonate. Stock solutions of sodium methanoate, sodium chloride and sodium ethanoate were prepared from Analar grade salts.
