Welcome back everyone to another video, provide the correct systematic name for the structure shown below. First of all, we want to classify the given structure and we understand that it is an alkane because we have a saturated hydrocarbon. Right. Now. The first goal is to identify the parent and the parent is identified by identifying the longest continuous carbon chain. And we can see that there are 123, 4567 carbon atoms in the longest continuous chain. So our parent is going to be hep, hep as a prefix means seven. And of course, we want to use a suffix A ne because it is an al cane. Then we went to enumerate the parents. And our goal is to minimize the locus. Specifically, the locus are those numbers representing where the substitutions are. We can see that carbon number three has two substituents. There are two branches, right. So essentially we want to enumerate from left to right, to make sure that we get as low lo as possible if we go from right to left. Well, we would have 1234 and five and we don't want to have five if we actually can have three. So we are basically saying that we are enumerating from left to right. Step number three is to identify the substitutions. And we can see that carbon number three has two subscriptions. There are two branches and those two branches are exactly the same. They have two carbon atoms. And we call this an ethyl substituent. So we can just state that there are two add the submissions. Step number four is to basically give the final name. What we should do is basically state the position of the carbon atom that has a substituent. We have three. And then we need to add a comma because there's another substituent which is exactly the same at carbon number three. So we're saying three comma three, we need to include a dash then because we have two ethyl groups, we're going to state die as a prefix, it means two. And then we will have ethyl. Since there are no more subscriptions, we basically want to finish the name with the parent. So we're adding the word Hep thing and this gives us the final name of this structure. Thank you for watching.
