Oxidation of alcohols

Oxidation of alcohols

Oxidation of alcohols. Acidified potassium permanganate (H + /KMnO 4 ), and acidified potassium dichromate (H + /K 2 Cr 2 O 7 ) are important oxidising agents. They will not react unless acid is present. Purple H + /MnO 4 - turns colourless when it has reacted.
