Accepted Answer

Welcome back, everyone. Our next problem says, provide the condensed structural formula of 24 di bromo one hexen. And we have four answer choices with four different condensed structural formulas. Since we're presented with the choices, we don't need to generate it ourselves. So let's just look at the name of this compound and work our way through these different structures and see which works for this name. So we have our base of the compound is hexen. So we have a six carbon chain with a double bond, it's one hexen. So the double bonds, we have six carbons. The double bond is between carbon one and carbon two. So with that in mind, let's see if that eliminates any answer. Choices. Choice A indeed shows the double bond between the 2nd and 3rd carbons. You can see here, carbon one is just a methyl group and then carbon two has the double bond. So choice A must be incorrect. Choice B shows the double bond between carbons, one and two. Let's count the carbons and see if we have six of them. We know automatically carbon one must be the one with the double bond. So 123456. So yes, correct. Number of carbons and double bond in the right place. Choice C like choice A has the double bond between carbons two and three. So we just cross that out right away. Now, let's look at D choice D has the double bonds. Well, it looks like carbons five and six, but of course, we can number our chain in either direction, so we can number it. number one on the right where we have the double bond, let's count if there are six of them, 123456. And there are indeed six carbons in this one with a double bond between one and two. So D is still OK by those criteria. Now, we look at the substituents, we have 24 di bromo. So two bromine's one carbons two and four. So let's look at structure B, we have a bromine on carbon two and a bromine on carbon four. So it looks like structure B will be our correct answer. Structure D has a bromine on carbon four and a bromine and carbon five. So this is incorrect because it would be carbon two if we started numbering our carbon on the other side. But our double bond needs to be from 1 to 2. So the bromine and carbon two needs to be the same carbon as has the double bond. So that's why choice D is incorrect. So our condensed structural formula of 24 di bromo one hexen is structure B. It has H two C double bond to ac with a bromine on it bonded to CH two bonded to CH with a bromine on it bonded to CH two bonded to CH three. See you in the next video.
