In this video we're going to talk about the methods we can use in drawing in an antumer. Now, when drawing enantiomers of a chiral molecule, there are two methods available. Now with method one, we're going to draw an image the molecule sees in the mirror. So let's just imagine this blue dotted line here is our mirror in this molecule is looking into it, it would see back its own reflection.
Now what would this look like? Well, we still have this carbon here in the center. You would see this NH2 still at the top and what else would it see? Well, it's looking in the mirror, so it see these two over here looking back at it. So we'd have the H with still the dash wedge bond, and we'd have our chapter three group, so we'd have it like this. Remember, we want to show the connection between the carbon carbon's, so it's best to draw it this way and then we'd have the OH back here. This new image that I've just drawn is the mirror image of my original molecule or its enantiomer. Remember, enantiomer is the mirror image.
Now this one method one is a little bit tricky because you have to look into the mirror and you have to draw it kind of like backwards. An easier method would be method 2. With method 2, all you'd have to do is you change your solid wedge to a dashed wedge and your dash wedge to a solid wedge on the chiral center. You Kee the molecule in place. The way it is O here, carbon would still be here. This NH2 would still be here. This OH would still be over here, and all we're doing here is we're inverting the bonds.
So now this dashed bond becomes a wedge bond and it has the H now. And then this wedge bond becomes a dashed bond and it has the Chapter 3 connected to it. In this method, we keep the molecule stationary in the same spot and we're just changing the bonds that show spatial orientation, right? So we could call this the inversion method for method two, right? So these are the two different ways we can draw the enantiomer of our original chiral molecule.
