Accepted Answer

All right. Hi, everyone. So this question says to provide the Iupac name of the given cyclo, all K note priority is assigned alphabetically to the attached groups. Option A says two prop one methyl cyclo heine B says two methyl, one propal cyclohexane C says one methyl, two propol cyclohexane and D says one propol two methyl cyclohexane. So first and foremost, right, recall that this compound is going to be a Cyclo alki because we only have carbon carbon, single bonds and we do have a ring structure present. So because of the presence of the ring structure, the parent chain of this molecule is going to be the six membered ring. So because there are six carbons in the ring, my parrot chain would be hexing. However, because it is a ring, right? Instead of saying hexane, my parent chain is going to be called cyclohexane instead. So now that we found the parent chain of the molecule, the next step is to add substituents in front of the name of the parent chain. Now, in this case, it happened that we have or it just so happens that we have two substituents, one of them contains only one carbon whereas the other contains three carpets. Now the one carbon substituent is a metal group, whereas the three carbon substituent is a prop group. Now, as the question, the question mentioned in the beginning, right. Priority is going to be assigned alphabetically to the groups that are attached. And the reason for this is because both substituents on this molecule are simply Ocu substituents, right? So there's no set priority of one functional group over another because they are the same functional group. So instead we're going to assign priority according to the alphabet. And so because the M in methyl goes before the P in propol, our methyl group is going to have first priority. This means that the carbon in my cyclohexane ring that's attached to my methyl group is going to be labeled number one. Whereas the carbon that contains my propal group inside of the ring is going to be labeled carbon two. And the reason why I wanted to touch on labeling is because recall that in an Iupac name, all substituents must be listed with a number to indicate their position on the parent chain. So when I arrange my substituents in alphabetical order, I'm always going to place their position number in front of it. So that's one dash metal dash two dash prop. Keep in mind that it's always important to separate numbers from letters in an Iupac name with a dash. So my final step is to write the iupac name as one single word with no spaces in between. And like I said, previously, all substituents are listed in alphabetical order with their position number before the name of the parent chain and again, with no spaces in between. So this yields an Iupac name of one methyl Torpy Cyclohexane, meaning that my final answer is going to be option c in the multiple choice. That's one methyl, two propal cyclohexane and there you have it. So with that being said, thank you so very much for watching and I hope you found this helpful.
