f. Structural representation of alkanes with molecular formulas indicating carbon and hydrogen arrangements.

Accepted Answer

All right. Hi, everyone. So this question is asking us, what is the name of the following? Alkene following the AAC rules. Option A says quad methyl dote or sorry, two quad methyl dote. Option B says 2266 tetra methyl heptane. Option C says 426 tetro methylene dodo and option D says 26 isopropyl heptane. So recall it our first step when it comes to Iupac nomenclature should always be to locate our parent chain and name it accordingly. Now recall that the parent chain refers to the longest continuous chain of carbons present in the molecule itself. So when analyzing the structure, given, I can see that there are seven carbons or rather the longest continuous carbon chain is composed of seven carbons. So because of this, the name of the parent chain based on the number of carbons is going to be heptane. So now the idea is to make sure that your parent chain is numbered appropriately because recall that the numbering of a carbon chain should begin from the end nearest to a substituent. But in this case, we can see that all substituents present are only one carbon away from the either away from either end, right? So because of this, no matter where you happen to number your parent chain, you're going to have the same location numbers for all substituents. But keep in mind that that is not always the case, right? So just make sure that you're giving all substituents the smallest number you can give them for their location. But with that said, we can go ahead and discuss what substituents are branching off of the parent chain. Now, as we can see here, we have four different substituents, all of which happen to be the same type. Now, when this happens, meaning in a situation where there are multiple substituents of the same type, there must be a prefix before the name of the substituent itself to indicate their amount. Right? In this case, we have substituents that are composed of one carbon and three hydrogens. So those are methyl substituents. No, because there are four methyl substituents. I'm going to use the prefix Tetro to indicate their amount. So that's tetra methyl. So now let's talk about position numbers because recall that every single substituent present must have a number indicating their location on the parent chain. Now, in this case, it just so happens that we have methyl groups on carbons, two and six and carbons two and six each have two methyl groups. So what that means is that I'm going to repeat those numbers twice each, the indicate how many metal groups are on each Carmen. So that's two comma two comma six, comma six dash tetra methyl. And notice the convention here, right. I'm using commas to separate numbers from each other and dashes to separate numbers from letters in my iupac name. So now my last step is to put everything together. All substituents are listed in alphabetical order before the name of the parent chain. Now, in this case, I only have one type of substituent. So alphabetizing isn't really necessary. So that becomes two com two comma six comma six dash tetra methyl and then goes the parent name te with no space in between. So my iupac name here is 2266 tetra methyl Heptane, meaning that my answer is going to be option B in the multiple choice and there you have it. So with that being said, thank you so very much for watching and I hope you found this helpful.
