So the first thing to notice here is that we have a ring, so this is going to be a cycloalkane. Remember when I told you guys that if you had a cycloalkane and it had one substituent, then you could omit the number? In this case, we're not going to want to do that because we have more than one thing coming off of it. This is a little bit more complex. We want to say the location of everything. Alright?
So the first thing is, what's the root going to be? Let's go ahead and just box this off because I know that came from the last example. What is going to be the name of this root? Well, the root is going to be a combination of a lot of stuff. It's going to be the number of carbons that are in this ring, plus it's going to have the word cyclo in it, plus it's going to have the two modifiers in it. Right? So I'm just going to start off with the easiest one. The root would just be cyclohexane. But after adding my two modifiers, this is actually going to turn into cyclohexenol. Does that make sense? Because I have a double bond and I have an alcohol.
Now what I have to do is figure out the locations of everything. So because this is a ring, I can start wherever I want. So where am I going to want to put my number one carbon, my number 1? Obviously, the alcohol. Why? Because alcohol beats all. So that means this is my 1, and now I have two options. I can either go counterclockwise or clockwise, red or green, depending on our rules of priority. What would be the next step? Which one would come next? And the answer is that double bonds receive more priority than halogens. So what that means is that the iodine might be really close, but the double bond has more priority, so the double bond is going to get my 2 here. And then we're just going to keep numbering around, so then I get 3, 4, 5, 6. So that means that if I were to name my substituents, what kind of substituents do I have? Well, all I have in terms of substituents is the iodine, so that would be a 6-iodo. Remember that double bonds and alcohols aren't called substituents. They're called modifiers. So that's my only substituent.
So now the only thing I have to do is figure out where the locations of these are going to go. What are the locations? Well, it seems like I have a 1 and I have a 2. So is it okay for me just to say that this is 1,2-cyclohexanol? No, that's not okay. We're going to have to put at least one of these numbers inside of the word so it's more specific what this is. Okay? So the one that I'm going to choose to put inside, you could pick whichever number you want. I'll just pick the 1. Okay? So what that means is that the final name here would be 6-iodo-2-cyclohexene-1-ol. Okay? But like I said, if you've made it 1-cyclohex-2-en-1-ol. That would have also been fine. Also, just so you know, some people put all the numbers inside. So another option would have been to say, this is getting annoying at this point, but cyclohex-2-ene-1-ol. That would also be completely fine. Alright? So any of these, any combinations of these you want, go ahead and use them. I'm going to stop telling you all the different combinations after this lesson because I think it's just a waste of time to do this every single permutation for every single name. But I did want you to see one example of me showing you everything. Okay? The one that you can't do is this one up here. That one just sucks because it's not specific enough. Alright? So very good. Let's go ahead and move on.
