Each of the structures in the previous problem has one or more substituents connected to the parent.
(a) Identify the name of each substituent in 4.39a.
Alright guys the first question we're looking for the names of the substituents in our molecule, first to figure that out, we need to first identify what the longest carbon chain is here, so it looks like the longest straight carbon chain or the parent is going to be right along here, okay? this is going to give us the eight carbons that we want in our parent. So, how do you think we should number them? We want to give our substituents the lowest number, so we're going to start up here, four, five, six, seven and eight, okay? This is our parent. Now, do you notice any substituents? let's highlight them, we have one here, it looks like a 3, another one down here at 4, okay? So, first we identify the parent chain and now our substituents are very clear, so what do you think we're going to give them as far as naming goes? We have one that's one carbon long and another one that's two carbon long, so what do you guys think? Well, the top one is going to be called methyl, right? Because it's only one carbon, it has that yl at the end for that substituent and the other one is going to be now two carbons, what you guys think? this one, since it's two carbons it gets ethyl, so the name of our two substituents for this compound is going to be methyl and ethyl. Alright guys, so hopefully that made sense.
