Alright guys. So, for this problem it wants us to convert this structure into a IUPAC name. Now, what you notice is that this is a Newman projection. Now, hopefully one that you guys have seen a few times because it's a little bit different to just a regular Newman projection that looks like this, right? The only difference is that over here, right? At this R and this R is connected to some other things, so we can just treat this the same way and what we're going to do to name the structure is we're going to try and convert it to a bond line, which isn't that bad and you guys, you guys will see why, so the first thing that we can do is start by naming how many carbons we have in giving them a number, so we can say that this carbon right here is going to be R 1, let's start with the back, okay? So the one that has that substituent we can call the one in the back r1, r2, right? This would be 3, 4, 5 and 6, so what this is indicating is that we actually have a ring, right? Because all these things are connected in this fashion, so we should expect a six membered ring. So, here's our six membered ring with 1, 2, 3, 4, 5 and 6. Now, is it missing anything? Well, it's missing that substituent. So, here we have our CH3. Now, do we know how to name this? Well, hopefully you guys realize that the route is going to be cyclo hexane. Now, we only have this one substituent to what we can call this is a methyl cyclohexane, right? So it wasn't that bad, the key to this is to realizing that this is a Newman projection but since there's two of them is actually any ring structure and all we need to do is count the number of carbons that we see remembering that that dot represents a carbon, right? this is a carbon and this in the back is a carbon and then we just fill in our substituent which is why we numbered. Alright guys. Well, hopefully this makes sense, this is the IUPAC name for this compound and just let me know if you have any questions.
