You then have to consider the effect of heating this (to a pretty high temperature, I would assume). 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. q skills for success 3 third edition answer
