 Let's talk about functional groups. I should have talked about it on the last video, but whatever you know what I'm saying So talk about functional groups now. So There's different organic molecules or organic molecules have different what we call functional groups, okay? And that's that area where reactivity is associated with and usually it has to do with I Don't know where the hetero atoms are. Okay, so If we look here, this thing's called ethanol all Or a reason, okay? Why because all alcohols and in this O well Ethanol like we call this alcohol like just in common parlance, right? We say I'm gonna go drink some alcohol or something like that, right? So That alcohol that we're talking about is ethanol, which is just one of a family of alcohol So there's methanol, propanol, butanol, you know, cyclohexanol all of these things are alcohols. They end in O well They have this group here this OH group, okay, that's bonded to a cart Okay, in fact the general structure of that is R OH Okay, so that's an alcohol Or it's just some sort of carbon is over there, okay? So it's just anything. So this anything you see that looks like this Anything that looks like this that's got an oxygen in the middle of two carbons like that To garbage with hydrogen So something that has the general structure of this We call an ether This stuff that we were talking about last last Time I guess that would be Monday, right? So Ether, right? So the ether that we were talking about when it was like the first day of the step, right? That's not Di-methyl ether. It's actually this other molecule di-methyl ether Okay, so Why is this also an ether because it's got this oxygen surrounded by these two carbons, okay? So you're going to be That's one thing you're gonna have to memorize about organic chemistry is these different functional groups And we'll go over a bunch of molecules and just say point out the functional groups. What are they called and today, okay? There any questions on those two functional groups? Everybody think they could pick out an alcohol and an ether. It's a psalm. Okay, cool
