WebCrO. 4. 2-butanol is a secondary alcohol compound and can be oxidized to 2-butanone by mild oxidizing agents such as PCC and strong oxidizing agents such as KMnO 4, K 2 Cr 2 O 7, K 2 CrO 4. Because 2-butanol is a secondary alcohol, it can be oxidized to 2-butanone (a ketone compound ). WebAfter adding a few drops of cyclohexanol to this pool, they can see clear signs of the oxidation reaction taking place as cyclohexanone is formed. This is a quick microscale experiment to illustrate that alcohols like cyclohexanol react with acidified dichromate(VI). No attempt is made to identify the product. The experiment takes about 15 minutes. the plug blue sherbert
