Alcohol Oxidation Mechanism H2CrO4 PCC KMnO4

January 21, 2016 By Leah4sci 6 Comments

Alcohol Oxidation Mechanism with H2CrO4, PCC and KMnO4 Leah FischOxidation of alcohols can be carried out by a variety of reagents.

The most common mechanisms you'll study in your organic chemistry course involve Chromic Acid H2CrO4, Pyridinium Chlorochromate PCC, and Potassium Permanganate KMnO4.

The video below shows you how each of these mechanisms will react with primary alcohols to form an aldehyde or carboxylic acid, and a secondary alcohol to form a ketone.

    Great explanation!
    I have a small doubt- In the Chromic Acid oxidation mechanism, when the ketone (or acid) forms, an electron gets kicked off onto the chromium (from oxygen) and the Chromium complex breaks off. What happens after to the Chromium after this? Does it get a negative charge?
    Thanks in advance…
