WebThe 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. WebOxidising the different types of alcohols. The oxidising agent used in these reactions is normally a solution of sodium or potassium dichromate (VI) acidified with dilute sulphuric acid. If oxidation occurs, the orange solution containing the dichromate (VI) ions is reduced to a green solution containing chromium (III) ions.
