Welcome back, everyone illustrate the structure of Isobel propionate and ether. We want to recall in this problem that generally we call ester in the form of alky. How can I wait? Now, let's understand what that means. Well, an ether group, it just carbonel bonded to an L kill group R one and bonded to an L cox group or two. Now, the alki group sr two and alkanna weight essentially corresponds to the parent which includes carbon number one from the carbo and all of the carbons from R one essentially in the longest continuous carbon chain, right, in this case, it says propionate. So we can actually call this tra Proano in a systematic naming if we want since we are given a common name. So we can essentially begin by drawing Coronel bonded to oxygen. Understand that oxygen is bonded to the alky group and our alky group is Isobel. Yeah. What is an Isobel group? Well, a beetle group is a four membered straight chain. An Isobel group is a three membered straight chain that contains an additional four carbon at the end of the chain bonded to carbon number two. So we have our iso beal substituent bonded to oxygen. And now on the left side of car bal, we want to have a total of three carbons, right? Because propane as an alkane corresponds to a three member alkane. So we have carbon number one, we have drawn carbon number two and we simply want to add that third carbon. So we have 123 total that's prop panel eight or propionate based on the name given to us in the problem. That's it. Let's label our final answer. Thank you for watching.
