The oxidation of secondary alcohols to ketones is an important oxidation reaction in organic chemistry. When a secondary alcohol is oxidised, it is converted to a ketone. The hydrogen from the hydroxyl group is lost along with the hydrogen bonded to the carbon attached to oxygen. The remaining oxygen then forms double bonds with the carbon. This leaves a ketone, as R1–COR2. Ketones ar… WebAn aldehyde always gives primary alcohols as the carbon [doubly bonded to oxygen} is attached to only one alkyl group whereas in case of ketone the same carbon is attached …
