Naming Alkenes

let's go ahead and add a few more functional groups. So now we're gonna talk about Al Keane's all kinds and alcohol's. So first, let's start off with the pi bonds with the double bonds in the triple bonds, Al Canes and all kinds are gonna be named by adding a modifier. So this is gonna be the very first time that were using a modifier in an AIPAC name. So I'm gonna teach you guys how to do this. So what that means is that instead of using the ending aim like we always use that stands for Al Cane, Okay, instead of using that ending we're gonna use, we're gonna modify it. Thio either be in if it's an AL Keen or Ein if it's an AL kind. Okay, so that's why we call it a modifier. It modifies the route name. Okay, so now all of a sudden ah, heck, sane becomes a heck sign if it has a triple bond in it. Does that make sense? Cool. So then let's talk about some important rules here. Al queens and all kinds are actually going to receive priority in numbering Al Keynes. This is also gonna be the very first time that now, when it comes to numbering the chain, we are going to give priority to this group. What that means is that I don't care about the closest substitutes. All I care about now is how do I give my double bond or my triple bond the lowest number of possible? Isn't that interesting? So now I'm just thing How can I make that number as low as possible? Okay, that's all I care about then. Finally, this could get tricky because thes double bonds go over two carbons, so sometimes it can be tricky. What's the location? Is that the first carbon or the second carbon? The location is always assigned to the first double bonded carbon or triple bonded carbon. Okay, so what I want to do here is I want to go ahead and name this compound. I want you guys to go ahead and try it first with the rules, and then I'll go ahead and I'll give you the name

so we're going to start off with the root chain, and that route chain would just be that. I mean, there's not really a whole lot of options now in terms of numbering. This one's interesting. So I could either make this my one in red. Or I could make this my one in blue. Both of them have something coming off of the first carpet on the red side. It's chlorine. On the blue side is dull, Bond. Which one is going to matter more? Remember that we said double bonds in trouble. I actually do have priority. So that means that it doesn't matter how close this chlorine is. I don't care about it. I'm going to go into this direction. So that means that I'm just gonna go in the direction that gives my bulb on the lowest number of possible. So that means this is gonna be that the dull bone is on one. Because we always give the the name the location, that bulb onto the first carbon in that double Bonder triple bond. And then this would be four and five. Okay, so it looks like this is gonna be a painting. Okay, hold it. Hold your horses. Just don't get too excited yet. I'm just going step by step. The route is panting The substitute Wint's are Well, we've got to It seems like we've got a four five die, chloral, All right, because we got two of the same substitue int And then finally, we have a modifier. So what is that modifier? The modifier is going toe change that came into Penn. Teen. Okay, later on, we'll do this all in one step right now. I want to show you each step. Okay? Also, we have to name with location is so the route all of a sudden gets its own locations. This would be a one painting. All right, so And that's because the one describes where the double bond is. So we're just gonna put this together. And the answer is 45 dich Loro one Pantene. Cool, right. Awesome. So that is it for that? Let's go ahead and move on toe the next alcohol
