So for this question, here we have another mono coronation here. So here we have our two metal butane and we have our chlorine gas and some heat. So that will, through a monarch coronation, which is adding one Korean to any of the carpets we have here. Your products would include be it have one like this. Listen, what would be the one that we'd see the most? Because it's on a tertiary carbon right here. Um, but we would also have things like this where we could have one on the secondary here. We would also have them on our primary, so we would have one here, one here and one here. So this one would be these two that I'm drawing now on our primaries would be we didn't see these, most likely because they're closer to this tertiary carbon. Where is our primary? That's all. The way over here by its loans himself is because we wouldn't see this one as often because further away from deter sherry carbon attached to a secondary carbon that's been attached to a tertiary carbon. So it like an extra step away so we wouldn't see this product as much as we would see these other two primary product. So here are all of the, um, products that you could expect to see from my model coordination as we are adding one corinne to any of the carpet. Um, so now are any of these Cairo so pretty much and all of the primaries are not the reason. Why is because we have one to hydrogen. So we have I didn't hear coming on. You have a hydrogen here coming off. So have 1234 Same thing here. So 12 12 and then 34 something here. And the definitions in Cairo is that there's four different things attached. And because we have to same Adam to hydrogen, these are not Cairo. Just go ahead. Not for this one. This one would be Cairo. The reason why this one would be Cairo is because this one has a metal. It has a isopropyl. We have three carbons over here. You have hydrogen hiding, and then we have a chlorine. So this one would be Cairo. So go ahead and mark that with red is a Cairo center here. Um, this one would not be karma sector And that's because we have one Michael here and one Michael here. So we have two of the same thing again. We have an ethyl over here, Rev. According. If one of these was like a nice appropriate or Romeo or iodine or even a hydrogen, then it would be. But because it's attacked, it has two of the same structure, so a metal, it's not a couple. So now we have figured out which ones that Cairo we have to figure out which of them are optically active. So we have this one that we have to look. So is this optically active? Well, we can't really tell. Technically, yes, it would be in one way or another, but it really depends on if it's wedged, or that we could have it wedged in front like this where we could even have it on a dash going away. So but because we don't have anything to show us, which is which, the wedge or dash? We would say that it's optically inactive because we can't tell if it's gonna rotate. You know, this way or this way. That's what the whole legend dash will tell. So any time that you see a wedge or dash, that's a good option to look out for or an s to see it optically active. But we can still have Chirau Ali, even though there's no rotation show.
