Oxidation of secondary alcohols yield
WebPrimary alcohols are oxidized to aldehydes or carboxylic acids if the oxidation is continued. Secondary alcohols are oxidized to ketones. Tertiary alcohols do not undergo oxidation reactions as there is no hydrogen on the carbon bearing the hydroxyl group that can be removed. There are many oxidizing reagents to choose from. WebA common method for oxidizing secondary alcohols to ketones uses chromic acid (H 2 CrO 4) as the oxidizing agent. Chromic acid, also known as Jones reagent, is prepared by adding chromium trioxide (CrO 3) to aqueous sulfuric acid. The Jones oxidation also uses acetone as a co-solvent in the reaction to prevent over-oxidation of the organic product.
