Problem 32 Medium Difficulty Show Video TranscriptAll right. So we have the following compounds here, and we want to go ahead and drop them and identify all the Cairo centers reach. So looking at Compound A, we have 24 dimethyl obtain, so I can go ahead and join what that's gonna look like. It's gonna look something like this is our obtain. We're gonna have a method to position and a method in the four position. And if we're going to identify the Kyrill centers, recall that a Cairo carbon is one where it has four different groups connected to it. And for this particular compound, we see that there is only one carbon where that is the case. And that is this one. Because we have to remember that there is a hit and hydrogen here, and so are four different groups. For this particular carbon is theme ethnic group, the hydrogen group, the S, a Pro Bowl group and the Pro Bowl group. So this would be the asymmetric kind of center. And because of this, um, we want to ask is the compound itself Carl And we would say yes. Because of that as asymmetric Carol center. So oops. Go ahead and say that we have one Carol center, and therefore the compound itself is Cairo. Okay, so we have a kind of a compound. All right. Looking at example be we're gonna go ahead and draw five F two or 33 dimethyl help. 10. So, what is that gonna look like? That is their help pain chain, and we're gonna have 33 di metal and then in a five Ethel. Okay, it's going quite that. And so we want to go ahead and identify the Cairo centers, and we might be tempted to think that, you know, three and five positions look like prime candidates for carnal centers. However, they have the same groups. Right? So at our three position, we have three. Ah, we have two different method groups, right? And at the five position, we have two different ethnic groups. So there is no carol center for this particular compound. So we would say zero Carol Centers. And although this is not ah, hard set rules, um, if we have zero, Carl centers for a simple hydro cane like this, um were generally going to say that the compound itself is a Cairo and so you'll see that once you get into later organic chemistry, you're gonna have smaller, complicated systems like leans and by finals. But in this simple case here, we're going to say that because we have zero Carl Centers we're gonna have on a car. A compound, Okay. And, ah, looking at example. See, we have cysts. Ah, sis. One for dyke. Laura cycle hexane. And so what is that gonna look like? So being going draw are simple, like wax saying here now, um, R 14 chloral remember, insists they're gonna be on the same sides. Doesn't matter whether we draw them both wedged or both dashed. As long as they are the same, it doesn't really matter. So here we have our cyst one for die Clorox saying they want to go ahead in the sign our, ah, Cairo centers. And we actually see for this particular compound that there are no Cairo centers. We might be tempted to think that these two are Carl centers. However, if you're going to go, you know, this side of the chain and this side of change direction. Same. So therefore we would say that there are no carol centers. Okay, So you would say that this compound has zero carol centers. And just like the rule we did before, um, we can actually draw plane of symmetry here as well. Kind of confirmed the fact that we are you actually gonna have in a car, a compound, But we could use the same line of reasoning that we didn't be where we have zero Carl centers and therefore we have in a car compound. But we also have that plane of symmetry. And so we're going to say that we have an acre compound here.

What is chiral compound examples?Molecules that are nonsuperimposable mirror images of each other are said to be chiral (pronounced “ky-ral,” from the Greek cheir, meaning “hand”). Examples of some familiar chiral objects are your hands. Your left and right hands are nonsuperimposable mirror images.
