provide the name of the following functional ized organic compound. All right, so what we have to do first is we have to recognize what functional group is this. What? We have a C double bond. Oh, single bonded toe on oxygen. Single bonded toe a carbon. That portion there identifies the functional group. It is an Esther. Now, remember, when it comes to an Esther, Okay, so let's say we have a long carbon chain here. We're connected to this. See Double Bondo. Then we have an O with the sea. And it could be longer. The way you approach naming. And Esther is this way. We're going to say that the OSI portion of the Esther is the Al Kiel Group of the Esther. So here, if we look at this Esther here, this would be the Al Kiel Group of the Esther. That's gonna form the beginning of the name. This Al Kiel Group of the Esther has in it. One, 2345 carbons in it. So it's out. Kill. Name would be pen tal. Okay, so panto because it has five carbons. So the beginning name of this Esther is panto. Now, this portion of the Esther, the C double bond. Oh, and then the carbon chain connected to it on the other side. We're going to say that this portion here, we're going to count the number of carbons and gain. It's al que name whatever. If it's plantain hex saying whatever and you're gonna switch the E ending because it's not an Al cane, it's an Esther. You're gonna replace the E ending with a weight. So here we have this portion of the Esther we're gonna count How many carbons that ISS. So it is one two carbons, two carbons. It's al que name is ethane. But again, it's not an Al cane. It's an Esther. So we're gonna change the E ending toe. 08 So it becomes pen tal Ethan, await all one word. So we're gonna take those two words and bring them closer together. So it's Penn. Tell Ethan. Await. So again, when you're naming and Esther, that's how you look at it. The oh, with all the carbon chains is one part that forms the beginning of the name. And then the carbon of the sea. Double bond. Oh, carbon, with its carbon chain, would form the end of the name count How long that portion is? Change the ending of the Al que name toe 08 And you'll have your Esther name at the end. Now that you've seen this one try to do the one that's below this one as additional practice. If you get stuck, don't worry. Just come back and take a look at how I name the next functional ized organic compound.
