WebChemistry of the reaction. We'll look at the reaction with ethene. Other alkenes react in just the same way. Manganate(VII) ions are a strong oxidising agent, and in the first instance oxidise ethene to ethane-1,2-diol (old name: ethylene glycol). Looking at the equation purely from the point of view of the organic reaction: 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. onyx ny instagram https://ciiembroidery.com
