Hey, guys, In this new video, we're gonna take a look at Halabja Nation. So here we're going to say that al keens and all kinds undergo addition reactions or adding to them, in which elements add across their pie bonds to create new Sigma bonds. Remember, Pi Bon is a double bond or triple bond. Sigma bonds are just single bonds now under Halogen Nation to Hala Jin's will add toe one pie bond. So we need one mole off X two for one double bond for one pie bond. Okay, so we need to halogen. So that's X two. So one mole of X two for every pi bon and here X can either be C, l or B are those tend to be the best intelligence because again, flooring is too reactive. Aydin is too slow. So here determine the major product from the following halogen nation reaction. So here goes. Are double bond it shared by this carbon here in this carbon here now, in halogen nation, what happens here is that double bond is broken so that each carbon can receive a halogen. So doing that, this is what we would get ch three this ch would gain one of those chlorine because there's two of them. The double bond is broken, but there's still a single bomb there. And then that ch two would also receive Ah, chlorine. So we would make here is a die Khallad di Howard meeting to Hala Jin's and not just die Halid, but something called a Fastenal di Hallett Vis any ALS refers to vicinity, meaning that the two halogen are on neighboring carbons. So again, the scene you'll die. How to refers to the same vicinity. The two carbons with the halogen, our neighboring carbons that's called the Fastenal Die Hallett. So we've seen this first one. Let's see if you guys could attempt to do this next one. Now here we have a triple bond, remember, we have two pi bonds. Remember, It takes one mole of X to to remove one pi bon. And since we have two pi bonds in the triple bond, that's why we require two moles of this halogen. So do what we've done before. Get a final answer, come back and take a look at my explanation and see if your answer matches mine. Good luck, guys.
