 Okay, so let's do another one of these predict the products of the following reaction. So we have an alkene here, and we have hydrobromic acid. So whenever you react an alkene with hydrobromic acid, the HBR is going to add to the alkene here, okay? So oftentimes what I, and we're just predicting the product, we're not going to show the mechanism, okay? But just to remind you, sometimes it's helpful for you to, okay? So do you remember Markovnikov's rule, okay? So whenever you have HBR or any of these H halogens, the halogenic acids, the H is going to go to the carbon with the most ages on it. That's called Markovnikov's rule, okay? And the BR is going to go to the other one, okay? So here we have these two carbons, and we have to decide which one has more ages on it. Well this one has two H's attached to it, and this one only has one H attached to it, okay? So the hydrogen is going to go to this age, and the BR is going to go, or the hydrogen is going to go to this carbon, and the BR is going to go to this carbon, okay? So let's just draw that out. So this carbon, the last carbon is now going to be CH3 like that, and that's going to be attached to CHBR, and then up here we have C2H5, okay? And if you wanted to, C2H5, we could expand, that's just a methyl group. So again, we're just predicting products here, we're not showing mechanism, okay? Is everybody okay with this? So this, whenever you've got an alkene, and one of these halogen acids, we're going to do an addition reaction, adds this to the alkene, okay? And it's going to add hydrogen, goes to the carbon with the most hydrogen. Are we clear on that? Any questions, maybe? No questions? Nobody even wants to say no, huh?
