In this reaction, we're gonna talk about the halogen Nation reactions here under this type of reaction, two halogens coming from either BR two or CL two are added to one py bond. So here we have our starting out keen and we're reacting it with X two in the process, each double bonded carbon gains one halogen. At the end of this, we have a structure that has two halogens on it which we call a die haid. Now, if we have in our kind, that means we have two pie bonds. So remember, we need one moive reagent for every pie bond. And since there's two pie bonds here, we'd need two moles of X two. So the first one would add, they give us two halogens and then the second mole would add again to give us another two halogens. At the end, you have a structure that possesses four halogens on it. So we'd call this a tetra haid. So remember, halogen halogen nation is just adding two halogens per pi bond within your structure. This could give us a diet haid if you're dealing with an alkene or a tetra haid, if you're dealing with an Alky.

Complete the following halogen reaction. So here we have our alkene and we're reacting it with one mole of chlorine. Remember all that's going to happen here is we're going to sacrifice our pi bond in order to add two halogens to my structure. Each double bonded carbon gets a chlorine here. It doesn't matter. The orientation that you place the chlorine if it's up or down or whatever, all that matters is the connection. It's these two double bonded carbons that each need to have their chlorine. Here, I decided to show them as being on opposite sides of each other, but I could easily show them being on the same side. We don't go into spatial orientation when it comes to a reaction like this. That's left for when we do organic one and organic two. For right now, this would be our die haid structure completed from the following halogen reaction.
