 Okay, so this molecule pictured up here is known as biox. It has since been discontinued from the market, but it wasn't and said that was popular a few years ago. But because of continuing health concerns, they've discontinued it. But for our purposes, we're just wondering some things about this structure. Okay, so can anybody help me out trying to figure out what type of functional groups there are in this molecule biox? Yeah, there's two areas. Yeah, or arrow groups or benzene rings, right? Okay, so let's cycle those. Let's find those ones. So aromatic groups. An ester, yes. Very good. So we see this cyclic ester here, right? There's a cycle there, right? So a compound that's in a ring, right? Or a piece of the compound that's in a ring. So the ester goes there. In fact, this is an alpha, beta unsaturated ester. When we learn more about different types of esters, we'll talk about alpha, beta unsaturated ones. But can anybody find another group in there? Yeah. So this thing up here, this is called the salt and the yield group. It's not one that you guys need to know for organic one, but so the salt and the yield group? Yeah. A what? An alkene. An alkene, yeah, definitely. So an alpha, beta unsaturated ester has an alkene next to it. That's what it means, alpha, beta unsaturated. So let's just write out which ones we're staying. So this is the ester. So for right now, you can write benzene group rings or aromatic ends of the molecule and then the alkene, of course. If you wanted to remember the salt and yield group. Let's see. I guess we could do some other things with this problem. Let's see. Actually, we'll do a different one. Let's kill this video and we'll do a different molecule and identify primary hydrogens.
