Alright, guys, let's continue with the naming of Al Keynes. So here in this next example, it's got a name, this structure. So what we gotta do here is look for the longest chain so you can go. 123 you go. 123 You go. 123 It doesn't matter which way you count. The longest chain is three carbons. So let's just make it simple. Ourselves will say that this is the longest chain, which means these two things here are substitue INTs. So that's a method here and a method here. And we want to count from the end one of the end. So we could say 123 or 123 the other way, we count from the end closest to the substitue INTs. Either way gets me there on carbon too. Now here's the thing. There's two methods, so that's dimethyl. Now I know they're both on the same carbon, but you can't say to dimethyl because to dimethyl means this to die. Method just means okay, there are two method groups and I know the location of one of them. One of them's on carbon too. But I don't know what the location of the other one is. So you have to actually say to to dimethyl, you have to state to twice, Okay, because each one is its own separate thing, located on carbon, too. We use die to pull them together because they have similar names. But each one is. It's an individual substitution. So we have to to dimethyl. And a three carbon chain is propane, and that's what we have named the structure. So keep practicing. Keep going all over all the different examples that we're going through.
