WebSo let's look at a different way to do it. In this case, we're going to use permanganate. So we take our alkene and then we take permanganate, MNO4 minus, so something like potassium permanganate. And usually you do this reaction in cold sodium hydroxide solution-- a cold aqueous solution of sodium hydroxide, so water's in there as well. WebAlkenes react with potassium manganate (VII) solution in the cold. The colour change depends on whether the potassium manganate (VII) is used under acidic or alkaline conditions. If the potassium manganate (VII) solution is acidified with dilute sulfuric acid, the purple solution becomes colourless. WebAlkenes are unsaturated hydrocarbons having Pi (π)-bond (s) between the carbon atoms, so they are easily oxidized by cold dilute alkaline solution of KMnO 4. When … baramundi mobile agent
