 Okay, so let's do this borohydration problem, so it asks what are the products of this reaction? So this is borohydrate THF, the THF part is just a solvent, okay? So that's not going to be participating in the reaction. So you can think of, in fact I'm going to erase all of this stuff here, so you can think of the active ingredient as just this BH3 here. So BH3 remember that the boron is less electronegative than the hydrodynamic, so it's going to add anti-marcogniton, okay? So the nucleophile is actually going to be the double bond here. So the boron is going to add to the side with the more hydrogens, okay? So which side would it add to? This, the right or the left? Right, because it's got more hydrogens. These are metal groups, right? Okay, so that's all right. But you know, right? Okay, so like that, and then that's going to all at one step, okay? So it's a concerted reaction, and it gives you, so it's concerted, and it gives you syn-addition, anti. So when we do that, hydrogen up there, right? So if the hydrogen's up, that means the BH2 has to be up too, okay? So I'll just draw that extra hydrogen. So what happens, this BH2 actually becomes BR2 by adding two more of these alkenes onto it, okay? So in fact, we could write, so we could say another alkene comes, another alkene comes, right? And those guys add to that BH2 to make it. So it's going to look exactly the same, but it's going to be BR2 now, okay? So what we can do is maybe in another video show what that actual complex looks like. It's very big, though, so it's hard to show on kind of a small board, okay? So then, well, that's the main step of this problem. In our book, it doesn't want you to know how to do the second step of the reaction. So remember, this gives you anti-Markovnikov addition of alcohol, okay? So you get an alcohol. So the second step, you just need to know the conditions. Hydrogen peroxide and hydroxide ions, so strong basic conditions. And that's going to give you the final product. We can go over that second step in a different video. So that would be your product, that secondary alcohol for this reaction. And we can go over that second step, but for the test, you all need to know, okay? Questions on that one? No? It makes sense. Okay.
