 Let's do this problem. It says most stable conformation of cis-2 tert-butyl cyclohexanol is a chair with the OH group, OK? And I guess it's implying that it wants you to determine where the OH group is axiolate for you, OK? So I'm just going to go ahead and draw the structure and then draw the most stable chair conformation, OK? And we can go from there. So it says the molecule is cis-2 tert-butyl cyclohexanol, OK? So cyclohexanol is that, but it says cis. So it wants some stereochemistry involved. And the tert-butyl is on the number 2 card. So it's going to look something like that. So now we're going to translate this into a chair structure, so like that. I just make this one 1, this one 2, like that. This one 1, this one 2, OK? So we'll do this one, where since this is up, right? At the up arrow, that means it's going up, so it's axiol, OK? If you want to, just to remind yourself there's a hydrogen there at the equatorial position. This one's up, right? And this is a down arrow, so the down is axiol. So the hydrogen's there, right? So the tert-butyl is actually what? Equatorial, very good, OK? So we're going to put it like that. In fact, this is the most stable conformation, because the tert-butyl group, that's a very big group. That's like the most sterically encumbering group, so you definitely want that to be equatorial, OK? So just to show you, right, I'm going to show the other chair conformation, OK? And it'll make this axiol, OK? And this one, equatorial, and that will be that. So in other words, if we do a chair flip, this conformation is much more favored, OK? So OK, that's 1, that's 2. So you see, now we've got that group equatorial like we would prefer it to be, but now this group's still up, but we chair flip, so now it's axiol. That's a huge group to be axioled, OK? So the most favored chair conformation is the hydroxyl in an axial position, OK? And the tert-butyl in an equatorial position. I think that's one of the answer tricks. Any questions on that one? OK, wonderful. I think the main point of these types of things is you want to find where's the biggest group, put it in an equatorial position, OK? And once you do that, put everything around it, OK? Oh, but it was a methyl group in there. No, no, still a methyl group is bigger, OK? Because you want to think it's C with three Hs on there, OK? And, oh, kind of as big as a carbon, but it's only got one H. So that was an N. That's still the same thing, OK? Yeah. Maybe whichever has the most substituent sum. You want to think more like a carbon group with more carbon groups off of that thing. Those are really sterically hindered. But anything like, yeah, so like more, if you want to think of it that way, yeah, more substituents off of that particular atom that's coming off of that cyclohexane, OK? Wonderful.
