Potassium permanganate (KMnO4) is a very strong oxidant able to react with many functional groups, such as secondary alcohols, 1,2-diols, aldehydes, alkenes, oximes, sulfides and thiols. Under controlled conditions, KMnO4 oxidizes primary alcohols to carboxylic acids very efficiently.

Explanation: Hydrogen peroxide, H2O2, decomposes naturally at a very slow rate to form oxygen gas and water. When manganese dioxide, MnO2, is added to a solution of hydrogen peroxide, the rate of the reaction increases significantly. ... Manganese dioxide catalyzes the decomposition of hydrogen peroxide.
