 Don't say that now. We're recording. Okay. So, first step. What's the first step? Acetyl formation. First step. Pro-mation. Pro-mation. Always. Why? Because it's fast, right? Acid base reactions are what? Fast. Fast. Okay. Draw the product. And I don't think we have much recording time, so I'm just going to get going through it. So, try to keep up with me while I'm drawing. You draw, okay? And if you can, it's not bad for you to do it. Okay, so what's the next step, Renee? I want to say the bond goes into the oxygen. These electrons bounce down there. Remember? That was the step that you're having trouble with. Okay, that's always that second step, okay? What did we do here? What did we do? We got that one. We broke that bond, right? So, that thing's flipped off, right? So, if you want to even, you can draw it like in a weird way so it doesn't make you think that it's still there. So, one, two, three, four. One, two, three, four. And we still have water there. What is this thing here? This portion? What have we been calling that? The super, what? Electrophile. Very good, guys. Like that. Hybridization to SB3, right? SB2 to SB3. And now this is that same kind of double deprotonation. So, we're going to have another water out here because this isn't going to deprotonate that. Got to deprotonate like that. And I'm going to erase that so I don't have to draw everything again. And then, so now that's got the proton. And now this thing's going to deprotonate. What's the next step? Well, let's draw the problem. Can I erase this step too? So, remember, this, I don't know if you guys have noticed, but this is essentially the opposite reaction of the last one. Right? Yeah, it's the exact same thing with opposite. Oh, crime. I should have told you all in equilibrium. All in equilibrium. Yeah, well, the acid based things, right? So, this step is not going to be in equilibrium. That's why I remembered. Or the next step, I guess I should say. The next step that we're going to draw. Okay? So, what is that next step? So, this step would still be in equilibrium. Or what is this step? René? What is it? It's the same one. Electron and the oxygen knock out that good leaving group. The thing's got a positive charge. It's a good leaving group. The way to get rid of it. It knocks it out. This thing's very close to it. It's just going to knock it out. Okay? So, what do we get there? One of our products already, right? That's one of our products, right? And then we got almost to the other product, right? That's like that. Then we have to regenerate the catalyst with two products. Okay? Any questions on that stuff? Remember, you're probably going to have to do one of these mechanisms on the test. So, make sure you know how to do an acetal formation and break down. The cool thing about this chapter is it's the same reaction over and over and over. You know, same thing. Well, it's protonation, kicking out the leaving group, nucleophile attacking the electrifying. Same three steps over and over and over.
