Condition of hydration of alkene

WebVideo transcript. Let's look at the hydration of alkynes. So we're going to start with a terminal alkyne over here. You can see there's a hydrogen on one side of our alkyne. And on the other side of our alkyne, let's say it's an alkyl group, bonded to this carbon on the right. So we're going to add water, sulfuric acid, and mercury (II) sulfate ... Web10.7.1 Syn 1,2-Dihydroxylation. 1,2-Dihydroxylation, the conversion of the C=C double bond to 1,2-diol, is an oxidative addition reaction of alkene. Osmium tetroxide (OsO 4) is a widely used oxidizing agent for such purpose. Potassium permanganate can be used as well, though further oxidation is prone to occur to cleave the diol because it is a ...
