WebChromic acid (H 2 CrO 4) oxidizes alcohols in aqueous solutions of sodium dichromate. It reacts with alcohols to form a chromic ester in which the alcohol oxygen atom bridges the carbon and chromium atoms. Thus, the ester forms by nucleophilic attack of the alcohol’s oxygen atom on the chromium atom.
