 Okay, so we're going to do something similar, very similar in this problem that we were talking about in that last problem where we're going to take a sp2 center and for the intermediate you know make a sp3 where it's going to have stereochemistry and then it's going to break back down to an sp2 center and it's not going to have any stereochemistry anymore. So yeah, you're right, we're going to have both enantiomers of that intermediate but both of them will break down into the same final structure, okay? So in this case, well I guess let's introduce the problem, right? So what do we got here? We're going to take an acid chloride and make an anhydride out of it, okay? And we're going to take that acid chloride and react it with sodium benzoate, okay? To anhydride, yeah, so let's erase, so remember, okay, so remember the sodium is just a spectator ion and it's kind of like you're going to get in the way of it, right? So the benzoate is going to attack the electrophilic carbonyl carbon just like that and here's what I was talking about, here we're going to make that intermediate, right? So you can tell if you look here that's a stereocenter but it's not going to matter because what's going to happen is this is going to break back down, these electrons are going to come back down and kick that leaving group out, you know, thus eliminating that stereocenter. So if you wanted to, you know, be super, you know, I don't know, nitpicky if you will about it, you know, you could say this, you know, put a wedge dash, you know, and then plus an antimic, okay? And that would be, I guess, more correct if you will, you know what I'm saying? But both of those will come back, take that, like that, and kick that guy out like that. Let's see if I have enough room here. And mechanisms on these small boards. Is that all in the video screen? Yeah, except for... Well, but can you push it over a little? Literally, like the...it's cool. You got it, you got it, you got it. Oh, okay. Cool. Okay, so you can see here that we could have put plus an antimic or a wedge dash, but it won't matter, right, because that thing breaks down. Oh, it's good, it's good. Back here, our sodium was associated with that, okay? And now it's associated with that. You see that? Put a line on this thing. See, yeah. So this...it's right there. So that's how you make an acid anhydride from an acid chloride. Okay, that's the mechanism. Yeah, it's the same mechanism over and over and over, okay? Is there any questions about this one?
