This website uses cookies to improve your experience while you navigate through the website. In an alkaline medium, KMnO4 reacts as follows - 2KMnO4+2KOH2K2MnO4+H2O+O. Of course many on here do, so its not really definitive, its just a birds of a feather kind of relation. But opting out of some of these cookies may affect your browsing experience. Although overoxidation is less of a problem with secondary alcohols, KMnO4 is still not considered generally well-suited for conversions of alcohols to aldehydes or ketones. Alkanes and aromatic compounds do not react with potassium permanganate. This figure is obtained by adding the individual molar masses of four oxygen atoms, one manganese atom and one potassium atom, all available on the Periodic Table of the Elements (see the Additional Resources section).
