Are there in this problem? We are given the molecular formula for four different molecules and were asked to draw the structural formula. And it's mirror image. And from that information determine which ones are going to be a mirror image. I summers so let's go ahead and get started withdrawing our structural formulas. Our first compound, a ch four. So it's structural formula will be carbon and carbon in the center, surrounded by four hydrogen. It's I am going to use a blue line here to represent my mirror. And I'm gonna draw the mirror image on the other side of that line. Yeah, okay, Alright. As we look at these two, we see they are the same on either side of the mirror mirror Image is the same. So this is not considered a mirror image, Isom. Er let's go on and look it. Let her be. Let her be. We have C f h three putting carbon in the middle if on one side and h on three of the other sides Um, trying our mirror in Let me draw my mirror image now. Okay, Right again as we look at this one, the original molecule and its mirror image are the same. So this is not a mirror image. I summer. Let's go on to let her see and let her see. We have C c l f H two right there is my image. It's draw my mirror and I'm your image notice this carbon has three different groups attached to it. It has a floor in a chlorine and then each of the hydrogen zehr the same groups there, three different groups. But notice now that I've drawn it, that's the mirror image and the original are the same. So again, we do not have mirror image. I summers letter d. We have c br c l f h right again putting carbon in the center. Keep my other things in the same places that I've been putting them. Not that that matters. All right, so there's the original structure. Here's my mirror. Let's see what we get. Now. Notice that this carbon has four different groups attached to it as flooring. It has hydrogen. Poopsie. Wait a minute. I messed up. One of these should be br All right. Sorry about that. That should be our. So it has flooring. Hydrogen bro. Mean and flooring. All right, so there's the structure and it's mirror image Notice. These two are different. These two are not the same thing. Therefore, this molecule does have a mirror image, Isom Er and that is because there are four different groups attached to it. There's a flooring group of bro mean hydrogen and a chlorine. Okay, Thank you so much for watching.
