Hey, guys, In this new video, we're gonna take a look at Hydra Halogen Nation. Now, under Hydrology Nation, a hydrogen and a halogen are added across a pi bon. So remember, hydro does not mean water. Hydro means hydrogen. So we're adding Ah, hydrogen in a halogen. Now, hear your book doesn't explicitly say this, but what we're doing here is we're following something called Markov Knockoffs rule when it comes to organic Cam, Russia and Germany and all these European countries have contributed a vast amount of knowledge in a lot of these reactions. One of the guys to help with this type of reaction was Markov Nankov. So they named it the Markov Markov's rule. Now, under my Kafelnikov's rule, you're gonna focus on the two double bonded carbons. You're going to say the hydrogen goes to the double bonded carbon with mawr. Hydrogen is on it, and then the halogen goes to the double bonded carbon with less hydrogen. So here, the re agent that we use in this reaction is HCL and HBR normally, But we could also use H F and H I HCL in hbr just happened to be the major forms that you'll see now again, I've said this multiple times. We get to organic chemistry. You gonna learn that hydrogenation is not as simple as this. And there are things called rearrangements that to occur here. Luckily, because you guys are learning the beginnings of organic chemistry, you don't have to worry about that. So just simply follow what I said here. This is just Markov. No cost rule Markov Makov Rule tells us h goes tome or hydrogen halogen goes toe less so knowing that we can use that Marco Viticultural to answer these questions. So attempt to do this one on your own Focus on the double bonded carbons which one has mawr hydrogen is directly connected to it will gain the hydrogen. The one that has less hydrogen is connected to it will gain the halogen. And when we're adding these two groups, what happens to our double bond? Knowing all of these things will give you the correct answer so attempted on your own and then come back and see how I approach the question
