Welcome back, everyone draw the in an tumor of the sugar shown below in its fissure projection. Now, we want to draw an inaner and we have to recall that according to the definition of in Antium, those are structures that are non superimposable mirror images of each other. So what we can do is draw the mirror plane. Then we want to draw a official projection and we want to draw the reflection of the manners with respect to the given airplane. Let's begin with co the first carbon. It is not chiral because it has carbo and the final carbon s to a wage, nothing changes. Those are on a vertical line for the remaining four carbon atoms. While we simply want to swap the subscriptions. If hygen was on the right now, we will observe it on the left. Once again, Hygen was on the right. Now, we will have hygen on the left, then hydrogen was on the left. Now we're going to get it on the right, followed by the final Harald position, it had Hagen on the left. Now we will have Hagen on the right and the remaining substituents while those are hydroxy groups. As we can see, the two structures drawn are essentially mirror images of each other. And they are not super imposable because they have those carl carbon atoms and no plane of symmetry. That'll be it. We have drawn the inaner of D manos, which is simply L manos, right? Because it's the inanimate of the mammals. Thank you for watching.
