 Okay, so this question asks us, an axial methyl group in methylcyclohexane suffers from what disadvantage? Okay? So, let's draw methylcyclohexane up here, and then of course when we see these options hopefully that automatically tells you to draw it in the charitable, okay, so you can tell what's going on. Okay, so let's draw it just in bottom line so we know what we're drawing in the chair form. Okay, so there's methylcyclohexane. Now let's draw our chair, and I'm just going to draw the chair form that has the methyl group in the diaxyl interaction. So that's with the methyl group axial, okay, so axial. So put that methyl group there, and remember the axial carbons that are on the same, or the axial positions that are on the same side of that methyl group, I want you to help me find them, okay? So, we're looking at carbon one, and that axial is up, right, so is carbon two axial, is that up? No. So, are we going to have any one-two diaxyl interactions? No. No, because this axial is down here, they're not going to interact, right? So already we can do what, cross out a couple of the answers, right, which ones? B and D. B and D, right? Because there's no such thing as a one-two diaxyl interaction, okay? There's only one threes, okay, so now we look over here, and how many diaxyl interactions is it going to have, how many other axial groups are there that this thing can interact with? Two. So this one's going to be down, where's this one going to go? Up. And there's a hydrogen in there, okay, and this one's going to go down, this one, hydrogen there, and this one? Down. Okay, so how many one-three diaxyl interactions are there? Two. Two, right? And one there. Because you can number them differently? One, three? Well, I mean, okay, this methyl group is trying to share space with these hydrogens. How many hydrogens is it sharing space with? Okay. Does that make sense? That's all it is, okay? So like, if I want to go sit, you know, next to Willie and Kenny here, right, and I'm going to, you know, sit on the same side of the table, I've got to interact with them when I'm saying, if I'm trying to get really close to them like this, they're going to be pushing me away. And that's what a diaxyl interaction is, you know, pushing me away. So it's not saying how many diaxyl interactions there are on the whole thing. It says, what disadvantage does that methyl group specifically suffer from? Okay? Because here we have one, two, and if we wanted to, there would be a third one. But that doesn't have anything to do with methyl group, okay? And of course the same thing is down here. But again, that doesn't have anything to do with methyl group, okay? And then if we do a chair flip, of course, methyl group's in equatorial and we won't even have that problem, okay? So which one can we cancel out now or which one do we want in a circle? Circle C. Circle C, yeah. So when it says one, three, is that numbering the carbons? One, two, three. One, two, three. Yeah, it's not like that, okay? Remember that numbering system for, this is just the relative placement of that. It's not like saying this is starting here and this is the second carbon and this is the, it's not like that. You're just saying what is the relative positions of these two? Okay? So don't let that confuse you. Because a lot of times people let that confuse you. Like, you may have substituents on the two position and the four position or something like that, but you could still potentially have them interacting. So watch out about that, okay? It's still called a one, three, diagonal in that case, okay? Yeah, does that make, okay. Okay, we're good. Any other questions on this particular problem before the video dies? It's about a killer.
