Hey guys. So, in this question we have this formula that was given and now I just combined it to a bond line, so it's a lot easier to visualize and we can go ahead and get our structures of numbering, so the first thing we want to do is always figure out the longest carbon chain. So, here we can go 1, 2, 3, 4, 5 and 6, right? You could have also labeled this as 5, 4, 6 if you want it but did you notice that we could have also numbered this a different route? we could have gone starting from over here and let's show that in a different color, so you could have given this our 1 this our 2, excuse me, that doesn't make sense, right? this are 2, 3, 4 and then 5 and 6 as you please, right? But, which one should we do? where we rather have the blue route where carbons have two substituents coming off? or we want to go to green route where at carbon 4 we have the two substituents coming off? we want to go the blue route and have our two substituents be at a lower number, so it's six carbons long, so we know it's going to be a hexane and take a look we have a substituent that's an ethyl and ethyl and another ethyl depending on how we did our numbering there. So, all these groups are the same. So, although this is going to be a 3,3,4 it's still going to be triethyl like this because all the substituents are the same and the last thing to do is include that hexane, okay? So, as you see it's a lot easier to first when they give you a formula arranged as it is to convert it to a bond line structure, so that we can easily number and figure out what our substituents actually are, because I didn't explain this but these CH3, CH2 groups either actually going to be ethyl groups, okay? Because a methyl will just look like this, it will just be a CH3 in parenthesis, okay? That would be an example for methyl group. Alright guys, so I hope this made sense, the correct name for the structure in 3,3,4-triethyl hexane. Alright, so let me know if you have any questions.
