Naming Anhydrides

Now we're gonna learn how to name and hydroids. So, guys, anhydride are a specific functional group that come up a lot in this section and there, one that you might not be very familiar with it all. So let's just back up for a second and talk about what isn't anhydride. Well, basically, anhydride is a carb oxalic acid derivative. So think of it as a car box late. But then you've gotten a seal group on the other side. Okay, so then you've got your carbon deal on our okay. And another way to think of it is that it's a die carbon deal with an O in the middle. Whatever you want to think. Okay. Now, in terms of naming the naming of it, um is gonna be visualized since this manner. Basically, when you look at it and hydride, it's actually kind of a combination of two car oxalic acids, right? You could say that maybe this was carb oxalic acid one. And maybe this was carb oxalic acid too, right? And maybe they came together and made it a hydride side note. That's actually how you making hydrates you make and hydrated by combining to carve oxalic acids into it and hydrate. So that's where the name stems from. So what we do is it's really easy. You just alphabetize your two different acids, visualized them with the carbon chains. But then, instead of ending with word acid, you would end with the word anhydride. Okay, Now, another special situation is what happens if your are groups are the same. So what happens if both sides of my hydrate or symmetrical Well, then you don't have to say that it's Carlos. Like I said, one car. So I said to and hydride, you could just say car oxalic acid one and hydride. So just Alcon, OIC and hydrate. Why? Because that means that you're assuming that one combined with another version of itself to make anhydride. You're basically saying that this is the end hydrate. You would yield through the condensation of thes two, um, car oxalic acids. Okay, so let me see. So obviously just going Really, I don't wanna mess up any questions for you, but this and hide right? I could name it as both the common and the AIPAC. Let's start off with AIPAC. So for AIPAC, I would have, um this would be, Let's see, ethanol IQ here. And this is propane OIC. Okay, so for AIPAC Oops. Let me give myself a little more space for AIPAC. It's gonna be ethanol IQ, propane, OIC and high dry, not acid. Don't make that mistake. Common. Common is going to be a C tick and pro beyond IQ. Okay, these the ones you're supposed to memorize. So again, alphabetical order. We're going to get acetic probe eon IQ anhydride. Now you see why it's so important to know those first five for the common names? Because they can come up with all of these derivatives. Okay, so that's it. Move on to the question. Let's see if you can get it right, and that'll give you the answer.

Alright, guys, let's start off with the easier side first, which I believe is this side. So this would be Ben's OIC, and you really have no excuse not to know that that's a benzo like acid. We know that that's what happens when it's on a benzene ring. Perfect. Now the other side is more complicated because we've got this double bond. So how would we name that? Well, with AIPAC, we have a way to do it, so let me show you. So for AIPAC, you would call this a four carbon car oxalic acid. So it's gonna be beauty Noack, acid beauty and no wick. Right. But on there's that double bond. It's in the three position. So I'm gonna turn this into three butin OIC. And that's the cool thing about AIPAC guys. Those modifiers that we learned a long time ago still work here. So beauty No, it That means I have a dull bun in the threes position and we're done. So then that would be combining that together. It would be in order, alphabetical order. Ben's a week three beauty no wick anhydride. Perfecto. Okay, so not so hard. Now, what about common How would common change? Well, guys, it turns out that you can't use like beauty. Eric, in this case wouldn't work here because I've got a double bond. And any time you have a modifier, your common names don't work because beauty Eric, that name trip wasn't designed to have an e n in it or an o l ending. That's one of the limitations. While common names, you can't change them like you can change AIPAC. So do we give up? No, Actually, this is another thing I'm getting at here. This actually this exact subsidy substitue int actually has a common name all on its own. This is one that you were supposed to know a long time ago from your first few weeks of organic chemistry. Remember that when you're attached directly towards Laban, that's called the vinyl group. But when you're one ch two away, notice about a ch two here that's called on a little group. So actually, there is a common name for this substitue int, and it's a common name you might see on your exam, so this would turn into in the common name. It would be a will Ben's OIC and hydrated. Okay? Again, Don't try to go down the beauty Eric route because butyric you can't account for that double bond because you can't change the name. You have to use a low. Okay, Awesome guys. So not that bad. Let's move on to the next question.

So, guys, if you know what you're looking for, this is a really easy question. Formic acid would be again that one. Carbon car books like acid so would look like this. So you could imagine that two of these things coming together, right? We haven't even talked about reactions yet, but two of these things coming together giving me anhydride is gonna look like this. There you have it. That's formic and hydrates. So notice that I did not say Die formic. It's for me because I'm just assuming that interacting with itself. Awesome. So let's move on to the next topic.
