Final answer:
Oxidizing a secondary alcohol under reflux typically converts it into a ketone, such as turning isopropyl alcohol into acetone using an oxidizer like potassium dichromate or a chromium-based reagent.
Step-by-step explanation:
The product of oxidizing a secondary alcohol under reflux is typically a ketone. During the oxidation reaction, the secondary alcohol is subjected to an oxidizing agent, which often includes compounds like potassium dichromate (K₂Cr₂O₇) or Jones reagent (a mixture of chromium trioxide and sulfuric acid). For instance, the oxidation of isopropyl alcohol, the simplest secondary alcohol, by potassium dichromate yields acetone, the simplest ketone.
When performing this oxidation under reflux, the mixture is heated with a condenser placed vertically in the flask to prevent the escape of reactants and ensure the reaction proceeds to completion. This process typically converts the hydroxyl group (-OH) of the secondary alcohol into a carbonyl group (=O), resulting in the formation of a ketone.
