WebA substance like potassium permanganate (KMnO4) combined with sodium hydroxide (NaOH) can be used to oxidize an alcohol into an aldehyde. While the NaOH serves as a catalyst, the KMnO4 functions as an oxidizing agent. The alcohol's C-H bond is broken during the oxidation process, and an oxygen atom takes its place to create an aldehyde. WebAldehydes are readily converted to acids with hexavalent chromium especially under aqueous acidic conditions, although potassium permanganate is the more frequently employed reagent. Ketones are, in general, much more resistant. Under conditions vigorous enough to bring about reaction, rupture of the carbon chain adjacent to the carbonyl ...
