Answers
The following model is that of an aldohexose: (a) Draw Fischer projections of the sugar, its enantiomer, and a diastereomer. (b) Is this a n sugar or an L sugar? Explain. (c) Draw the $\beta$ anomer of the sugar in its furanose form.
So for a we'll start off with. So then we will have, um this future production. And this is L manos. Then we have, um, in in anti armor and this is de manos. And lastly, we have a di stay over. And this is the glucose. For some reason, my pin won't work on top of the molecule. Well, they were You well does not see age Oh, on the top. And then you get to be, um so the model represents, um and l adult excels because the hydroxyl group on the Cairo carbon farthest from the album Tiger Point so left so high drugs Whole group on the Cryer, all carbon farther from the Allied group Points left and I said We have seen poses tricky The Fury Nose ring oven Alba Alba Hyksos is formed by connecting the O age group at the sea For the Allied Carbon, the best way to draw the anima is toe lie l manos on its side and form the ring. All substitutes point down in the Fury knows in an America wage in the C h. A wage stage 20 age groups RCIs So it'll look something like that
All right, we are on problem 10 again. Were given were given a three D model and we're supposed to convert out to a fresher configuration and or Fisher projection and the name that sugar. And also, um, specify if that's a D, um, sugar or anel sugar. So again, I can't have the picture from the book and the screen. So what I'm going to do is try to redraw that and the Tetra Hydro confirmation and then will convert that to a Fisher projection. OK, so according to the model, we have five carbons, So one to three four and then five so that first carbon has on oxygen, double bonded to it and a hydrogen off to the site get. And then we have a hydrogen going into the board and, ah, no age group going out of the board and the next we go to carbon three. We have a no age group, after all, color location. We have a no each group into the board in a heart surgeon going out next again. We have a no age group going out of the board again, and a heart surgeon coming into it aboard and finally um, we have too hard agents. One is going into the board and one going out of the board and another hydrogen or sorry. A, um, an alcohol group come in the same plane. So, um, looks like we have a sugar right, which is actually specified in the problem. And we're trying to do, um we're trying to make this into a fissure projection. So, um, as usual, this all those would be or this this all the hide would be your carbon one. Okay, so you have that c h o in your Fisher projection, and we have three Karol centers in between before we get that C h 20 h. So this is this Is that th do a witch? Okay. And then, like I mentioned, we have three cardinal centers in between. So 123 Right. So I want to look at this from the top view. Okay, So this is our of you, right? So this is your eye looking down. So, um, from that perspective, received that carbon after, let me go ahead and number our carbon so we don't get confused. Okay, So from our numbering, and if you look at it from the top. You see that carbon to in carbon four or not? I'm kind of in the right rotation for a Fisher projection. So we have to rotate them up. Right? Because that's just how a fisher projection is drawn. Okay, so if we do that for carbon, too, um, sins since the alcohol group IHS right now going out of the page, If you flip that carbon, it's gonna go into the page. And from your perspective, that's going to be on the right side. Right? So that's gonna be in the right side. And you're hydrogen on the left. Um four carbon three. Though, since we're not slipping anything, I think this makes it very clear that the alcohol group is on the right side. Anthee, hydrogen is on the left side. Okay, So, again, you're looking You're looking down. Okay, so you're left side. Okay, So I left side would have the wedge from, um, the tra. He'd RL confirmation Detrick, a jewel structure and your right side is gonna have the dashes. Okay, So, looking at carbon four right now, um, your alcohol group looks like it's going to be on the left side but again, since this is not the right rotation or right position for the Fisher projection were flipping that carbon four. So instead of being on the left side, you're alcohol group is now going to be on the right side, okay? And that hydrogen is going to be on the left. Okay, so that would be our Fisher projection for the sugar. And hopefully you dio recognize this. Ask your wry bows. Okay, so five carbon sugar. So that's your rivals. And according to this, um, last Cairo carbon. Since our alcohol group is on the right side, that makes it our de rivals the rebel. So there you have it. That's our answer for this problem.
Students today, we're going to be answering this question where they want us to convert each of the following her heart roof projection to a vent chain form any Fischer projection and they want us to name the Mono Sakurai that we've drawn. So so I'll do one for example. Um so the one that I'm going to do like mhm I wonder if I wanna do one or 2 like, you know, I'll just do two, I'll do two. Okay, so the one that I'm going to do is groups. So they want us to do a hardboard projection but it's an open chain so how they want that is sure. Yeah. Make sure you got the carbons and there. See she? Okay. So With this one I'm gonna make and here yeah, no here to ch Okay, help page. Sure. We check to make sure this is upper Town. Okay. Okay, so that would be down, this would be up. Okay. Right, mm. Mhm. On the way, this will be up. Okay. Just make some reason. Right. Yeah. Mhm. Yes. No, this would have to be done. Okay. Okay. Sorry misery. My Noakes. Uh Okay. This L. H. Scaring. Then we got to see H. On H. Yeah. And so did the hard work and then we're gonna do it open now we're gonna do a fisher. So the fisher I'm going to do just like this. Yeah. Yeah. Mhm. So that's 1, 2, mm. Mhm. Yeah. Yes. Yeah. Okay. Yeah. Yeah. Mhm. Okay. Yeah. Mhm. Mhm. Yeah. Uh huh. Yeah. And then we're gonna have our beach bitch leach uhh help H. And H. H. H. two H. Right. Mhm. So right here what I drew I drew. Uh huh. The girl clothes. So that's one example. And we can do one more example if yeah we could do one more example if you want. Well another example. Well that's just one way how you can do it. Yeah we do another example. We have time. If you will only to see another example or if you've got the hang of it then you can drop you can stop the video if you want to. So another one we can do. Yeah. Right. Yeah. Yeah. Yes. Three. Yeah information. Wait stop on shoot. Yeah. Yeah. Oh I put the original rock spot hold on. It's supposed to be up here and I'm gonna draw our fisher. Yeah. Yeah maybe they're supposed to be a C. By you know what it's okay. It makes it look fancy. Just remember this is A C. And not to eat. Okay. Sure. Okay. Yeah. Mhm. Yeah and with this one it might not bring it up in the book but this is um the L. Trolls and yep that is it. I hope you found it very helpful and please take care. Okay bye.
How old their students today, we're going to be answering this question where they want to convert each of the following? Hard for projection to an open chain form and uh Fischer projection and after you do that, you have to name them all separately if you have drawn. So let us begin. Okay. So when they were mentioning the question, I didn't realize they had to put place there. So added there. So now we're going to show how the set up of work. So let's try to part A so how we're going to show it as an open chain. How are you gonna do that? Is where this one ends up, oops going away and to make it more balance. Um you're gonna have the h that's basically gonna go here basically for that line. We move it here and for this. You want the moving it down here where you're gonna get an open chain that will look like, let me see if I can do this, right? You're gonna get a set up. It's gonna look something more so like this. Okay. Yeah. Yeah. Yeah. Okay. Took here if you don't screw them down. Yeah. To beach and how Yeah, R. O. H. Bottom and then how we're going to set up our Fischer projection, we're gonna start up clear. Yeah, it's gonna be a mhm See Okay, okay. Forget the double pawn. We're going way too fast, slow down. Okay. Yeah. Yeah. Your hybrid cloud H preach. Okay. Yeah. Yeah. H is here and let me scrub there. Yeah. Mhm Hi. Yeah. Mhm Yes. Not yet. Okay. Yeah. Yeah. yeah. Okay good purpose, any statement to uh reach so with this type of set up um what would be the name of this Monos Ackroyd. Well this looks like it could be okay pale the way, how does this set up and then let's go to part be, how is set up where I can break that up. Yeah and some of the movements I'm doing this is something kind of will learn um and or go one or two or go one. That's how you, I'm sorry I'm doing a little bit to the fans but that's just only you get the movement. Yes a little bit teacher I learned from or go Uh one and two even though I'm gonna do really well and that so I might be doing it wrong but yeah. Yes. Host slow. Okay now it looks better. Okay so then we get our. Oh I see oh look and H. O. Yet age. Age yeah here her speech Oh paige let me see. No in the age they will get our yeah L. H. If you can. Sure. Yeah. Okay so now we're going to stop our fisher diagram. Mhm. Mhm. And I'm just gonna go by how the age is set up smokers now our siege two more age so up here so we can put our h here now each over here to old age like a try heating dependent on each over here the age in that last right? Mhm. Yeah, well, that's great each year. Uh H so look at this setup. Okay. I'm trying to get that fit, which um mono Zachary would fit for that. Um no supper, rye, that will fit with. That would be your, it looks like I said with the go tos. Yeah, and, yep, that is it. I hope you found this very helpful and please feel free to look at the content from other creators I go for and explain whatever tractor questions you need extra help with. Okay.
