Naming Alkyl Halides

so I've got some good news. We're all done with Al Keynes. The bad news is that now we have to add some functional groups to the mix. All right, so the first and easiest when we're going to start off with is alcohol highlights. Alright, so alcohol. Hey, Leads are simply named by adding them as a substitute went before the root chain indicating their location. Okay, So what that means is that Remember that at the beginning of this lesson, we talked about substitutes and modifiers. Alcohol lights don't have modifiers there. Just called substitue. It's just like an Al Cain would be like alcohol or whatever. Okay, So one thing we should know is are prefixes for these different intelligence. So floor florin would get the prefix Floro. Okay, chlorine gets the prefix. Claro Roman gets the prefix, bro mo, and then iodine gets the prefix. I Odo okay. And these are gonna be the prefixes that we use to assign the name to the alcohol. Hey, lied. Okay, um, the next thing that you should know is that alcohol highlights have no priority Zero priority when it comes to numbering the direction of the chain. So What that means is a lot of people think Oh, I've got this long chain and this site has a chlorine on it. So that must be the side that has the one that I start from. No, not at all. Use the same rules that we did before. Just you look at the closest substitute. It doesn't matter what it is. It could be a chlorine. It could be a metal. It doesn't matter. You still give your lowest. You're still make the chain start from the side. That has the closest substantially. So what I want to do is apply this to this alcohol. Highlight a go ahead and try to solve it out on your own. First draw it out. And then when you're done, you have your answer figured out. Then go ahead and go to the next video.

Alright, guys. So this one was actually similar to one that we did earlier. Where it kind of looks like a Turk. Beautiful. But it wasn't My longest chain would look like that. So that would be, um it looks like six carbons. 123456 So my route is gonna be heck sane. All right, Now have to decide which one gets the number one. Is it read, or is it blue? And for this, I need to go ahead and see which one is the closest Substitue int read has a substitute on to Blue has a substitute on two. So far, there's a tie. It's going to go to the next substitute. Wint's Red has its next substitute on five. Blue has its next substitute. I keep doing that still on, too, because there were two metals in that location. So it turns out that even though the iodine is all the way over here, my number one is still gonna be the blue. Okay, So what that means is that Now look at substitue INTs. So for substance, what I got? I've got a 22 dime, Ethel, okay? And it looks like I also have Ah, five I, Odo. Now all I have to do is piece that together, Um, in terms of alphabetical order, which one would come first? Remember, die doesn't count. So I look at em versus I and I comes in the alphabet first. So it would be five iota to to dime Ethel hex it not so bad right now, So hopefully if you have questions, let me know. But if not, move onto the next question. Now, I'm just gonna let you guys know the hardest part about the next question is actually just figuring out which chain you're gonna use. So I want you have to pay extra careful attention to that because this one's a little bit tricky, So go ahead and get started.

Like I said, hardest part of this one was just figuring out which chain we're going to use as a route chain. So let's go ahead and look at the different possibilities. Um, so I could have used this blue chain right here. That would have been one option if I use that blue one. How maney subsistence would I get to? So I'm just gonna say Blue equals two. Okay, I could have also used this red one down here. Okay? Now, keep in mind that that red one down there is the same thing. As if I would have made it go down this way, like here because both roads lead to the same place. So how maney subsections would that have had that would have had also to Okay. Lastly, we could have also done this. How many substitutes would that have had if I made that my longest chain, that would actually have three. So it looks like Green is gonna win, and that is gonna be our longest chain. All right, so if you didn't get that as your longest chain, you already got the question wrong. That's why I told you guys to be really careful about which one you pick as your longest chain. Right now we have to figure out which side is going to get the number one and which side is going to get. I guess number five. So is it gonna be number one here in red or number one here in blue? Okay, so the first thing I do is I look at closest substitue INTs. So blue has a substitution in the to and red also as a substitute in the to does bro me and beat metal? No, Like that, Z, I don't even think about that yet. I'm just thinking closest substitue INTs. There's a tie. What do I do? In the event of a tie, I go to the next substitutes. So now I'm gonna go to three and three. Has a substitute. Went there for blue, but check it out. Three also has a substitute on this side for red. So we've got that rare situation where there's a perfect tie because the substance are symmetrical. Okay, so not only can I not determined by the first substitue int if I go through all the substitutes, it still doesn't tell me. So now What I need to do is I have to use what rule toe, determine. Um, the direction. And that's the last rule, which was alphabetical order. Remember, this is actually I think rule number two. The last one said, if you can't decide the news alphabetical order. So now what I'm gonna do is I'm gonna erase all this stuff that has to do with closest substitue INTs on. I'm just gonna say which one is gonna win in terms of alphabetical order, bro. Ming or metal. So now you guys realize that it's gonna be bro me. Okay, so that means that my route chain or my parent is gonna be plantain. And what are my substitute wants? Well, my substitutes are gonna be I'm gonna have a two. Romo, I'm gonna have a three Ethel, and I'm gonna have a four metal notice that I couldn't use Di Tri Tetra because all of these air different, so I can't use those now. All I have to do is put these in the right order in a big name and I'm done, and that's actually just gonna be in alphabetical order, which it already is in. So it's gonna be to Romo. Three Essel form Ethel painting Tricky. Right. So I hope that you guys got that. But if you didn't get that just considered a learning experience, you need to be very. You have two very concerned with which one is your longest chain. Which direction are using before you can start, actually putting the name together. All right, so let's go ahead and move on.
