15.7: Oxidation of Alcohols - Chemistry LibreTexts

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. Why is cro3?

WebThe rate of oxidation varies between primary, secondary and tertiary alcohol. On the basis of their oxidation rates, alcohols can be distinguished as: Primary alcohol gets easily oxidized to an aldehyde and can further be oxidized to carboxylic acids too. Secondary alcohol gets easily oxidized to ketone but further oxidation is not possible. WebAlcohol Oxidation Reactions with PCC. PCC is a milder oxidizing agent than Chromic Acid. It will only oxidize a primary alcohol a single step to produce an aldehyde. This is the major difference in the alcohol oxidation reactions of PCC and Chromic Acid. And just like Chromic Acid, PCC will oxidize a secondary alcohol to a ketone.
