Accepted Answer

Hi, everyone. Let's take a look at our next problem, provide the structure of the following molecule iso butyl ether. And we have four different structures labeled A through D. So let's look at our compound name and think about what the structure would look like to match it to one of our choices. So we have an ether. So we know with an ether, the two parts of the name before ether are the two R groups. So we have an Isobel group and a phenyl group. Well, the phenyl, of course, is our benzene ring and we can see that all four of our answer choices have this correctly bonded to the oxygen that makes up the ether. So the phenyl component and the ether component are present in all of our answer choices. So we just need to correctly identify the iso butty group. And these do get a little confusing all the different beetle groups. But let's think about the fact that it needs to have four carbons and Isobel similar to Isopropyl, you get this sort of y shape structure with two methyl branches at the end, but we need four carbons. So if we think about that. We have our O I'm just gonna put ph for the fennel. So we have carbon one and then because it's file and not propol, we need another carbon two. And then we have that little what looks like a Y, two methyl groups. So we have a total of 1234 carbons with that branch structure. So which of our structures is correct. That would be choice c where you see we have that 1234 with the two methyl groups in that Y shape. When we look at our other answer, choices, choice A coming from the oxygen, we have our next carbon and then we have a methyl branch and an ethyl branch so unevenly divided. So if you think about this four carbon chain that's attached to the oxygen, it's attached at one of the central carbons or at a secondary carbon. So it's attached to a carbon as a bond to two other carbons. So that makes it not Isobel, but sac beetle, the sec for that secondary carbon. So SEK beauty fennel ether or either. So that's why choice A isn't correct when we look at Choice B and we look at that branch, it is another beetle group, there are four cars but they're attached in this sort of trident shape. So the carbon that the oxygen is attached to is a tertiary carbon with bonds with three other carbons. And so in keeping with that this is a chart be not an Isobel. So that's why choice B is incorrect. Choice C is our correct answer. Choice. And then choice D, when we look at the carbon chain that's here on the other side of the oxygen, it has too many carbons. It has an ethyl group and two methyl groups. So it has 12345 carbons. So wrong number of carbons in that branch. So that's why I choice D is not our answer. So once again, the structure of Iso butyl Fenny ether is Choice C with our F group and our Isobel group. See you in the next video.
