 Okay, so this problem says, draw both chair confirmations of cis-1,3-dimethylcyclohexane and indicate their relative energies and circle the more stable of the two conformers, okay? So it says cis-1,3-dimethyl, okay? So the first thing we want to do, well, not the chair, yeah, just the cyclohexane structure, right? So, online structure and then from there, we need to find the relative positions, 1 and 3, right? And it says, can't remember, it says triangle, no, cis, right? So cis means what? The same side. So they're both going to be pointed which way, right? Up or down, doesn't matter, okay? So they can be wedges or dashes. I prefer wedges, so that's the way I'm going to vote. We don't have to do it. Okay, so it wants to, when it says the more stable conformation, it's talking about the chair conformation, that's what it's talking about. So we need to convert this to the chair conformation. So remember, 1, 2, 3, like that, draw a chair. So the first one, what is that, up or down? Up. And this one? Down. Up. Up. Okay, so if it's up there, it's got to be what, over here? Up. Up here, right? So I like to start here as carbon 1, so what is it going to be, axial or equatorial? Axial. Axial, because axial's up. Axial. So that's a methyl group, that's 1, 1, 2, 3, okay? So this one is up here, right? So what is it going to be here? Up. Up as well. So is it going to be axial or equatorial on three? Axial. Axial. So would you expect that this would be a very stable conformer? No. No. Why not? It's got a large axial position. Yeah, you've got a large 1, 3-diaxial interaction there, remember? So remember this, this bad interaction, these two groups, called 1, 3-diaxial. So what's going to happen when we ring flip? Tell me about that. Yeah, so they go from axial to what? Equatorial. Equatorial. What do they do? Do they go from up to down? No. So they stay up, but they go from axial to equatorial. So ugly chair, but whatever. So up, I like to put it there, right? So which way did we say it was going to be? Up. What? Equatorial. Equatorial. So where would I put it? Yes. Best, right? Okay, so remember parallel, that guy, order that guy. So 1, 2, 3, right? Which ones? Where is this going to be? Equatorial. Up, equatorial. Very good. That's very good. Very impressive. Okay, so are these equilibrium arrows? The way I'm showing you, is that correct? They should be equal? No. Back and forth? Which way should they be? Point and twist. So the right, right? Because this isn't going to want to go that way, right? Because this is steric hindrance because of that, right? Diaxial interaction. So if we wanted to do it. So I think it says, what's going to be? Equatorial. Equatorial. Equatorial. Equatorial. Equatorial. Equatorial. Equatorial. Equatorial. Equatorial. Equatorial. Equatorial. Equatorial. Equatorial. Equatorial. Equatorial. Equatorial. Equatorial. Equatorial. Equatorial. Equatorial. Equatorial. Equatorial. Equatorial. Equatorial. Equatorial. Equatorial. Equatorial. Equatorial. Equatorial. Equatorial. Equatorial. Equatorial. Equatorial. Equatorial. Equatorial. Equatorial. Equatorial. Equatorial. Equatorial. Equatorial. Equatorial. Equatorial. the opposite of what you did on the first one, as far as the axiol equatorial. Yeah. Yeah, so this is cis, right? It's not like we performed a reaction, right? We just did a conformational change, okay? So we didn't perform a reaction that we couldn't have changed what the molecule was, so it's still a cis isomer. Any other question?
