 Okay, cool. So, let's do the mechanism for the formation of a hydrate, okay? And remember what we talked about just the last problem, right? We're looking at the interplay between nucleophile and leaving group. So a lot of times you'll see these equilibrium areas showing like this, okay? But they don't necessarily mean that it's a 50-50 equilibrium, okay? In fact, if it was like 46-54, you'd still show something like this. But sometimes you would like to say which way would this equilibrium line, okay? And it's all about this interplay between these two things. So remember, what did we talk about? What were bad leaving groups? Some of the atoms are nucleophiles that would be bad leaving groups. Carbon, definitely. What's another one? Anything that's a hydrogen. Hydrogen, okay? Those are the two that I want you to remember, not anything, anything. Hydrogen, carbon, okay? Is oxygen, hydrogen, or carbon? Okay, oxygen is very similar on scale, right? Where the periodic table to the halogens. Remember the last thing we talked about. The halogens are very good leaving groups, right? Water here is a what? It's a stable molecule, right? Okay, we can force this to happen. We'll talk about that later. But let's just look at the mechanism of this. Usually this mechanism is going to actually lie to this side, okay? Because like we've been saying, water is a stable molecule. Oxygen is both a good nucleophile and a good leaving group, but when it's not negatively charged, it'll be a better leaving group, okay? So let's do the mechanism here, okay? So the first step, of course, remember, the electrophilic carbon. So this is, a lot of times that'll be the first step, it'll be either attack of that electrophilic carbon or this getting programmed, these electrons on the oxygen getting protonated to be that super electrophile that we talked about. There is a very, very, very bad tendency for introductory organic students to want to take the hydrogen from there to there, okay? And it can't do that, okay? You gotta take it from another water molecule, okay? So what's going to happen? And you could think of it either way, these two steps happening, one probably like that. So you could probably think these two steps may or may not happen that way if they could be switched because you can deprotonate or probably, but are there any questions about that one? So remember, the reason that we would think that this might lie more towards this way is because there's nothing forcing it this way, okay? This isn't really a super electrophile because we don't have that proton up there, we don't have anything making that a very, very positive carbon, okay? Also, what did we talk about? Water, not really a very good nucleophile, but it's a very good leaking group. Why? What do we say about it? Stable. Yeah, it's stable, that's easy. And as you remember this stuff, very similar to the last one we did. Any questions? Okay, tell us.
