Hi there.
00:03
In this question, we are asked to name this organic compound.
00:07
And what i have written here is just the carbon backbone, because this is a hydrocarbon.
00:12
So when naming it, we just look at the carbons.
00:14
We know that the rest of the bonds to each of these carbons are filled with hydrogens.
00:18
But we do not need those for the name since we've identified this already as a hydrocarbon, meaning it's composed of just carbon and hydrogens.
00:27
Additionally, we notice that there are all single bonds in this.
00:31
So that means it's a an alkan.
00:33
It's a member of the alkan family because it has all single bonds.
00:43
And what that means, since it's a member of the alkan family, is that the name, when we name it, is going to end with a &e.
00:50
We'll have the suffix a &e.
00:53
Okay, so let's go ahead and proceed with naming this.
00:56
The first thing we need to do is count how many carbons there are present in the longest continuous chain.
01:03
So the longest continuous chain, we can either do the five carbon straight across.
01:08
Or we could bend it, but we still get five that way.
01:11
So i'm going to go ahead and just call this our longest carbon chain.
01:18
So this has five carbons.
01:22
And five, the prefix for five, is penta.
01:28
So putting penta together with a &e, we see that this is a pentane.
01:37
And by writing pentane, we have just named that five carbon chain.
01:42
All right, the only thing we have left to do is to name this branch that's coming off.
01:48
So this branch is made up of just one carbon, and the prefix for one is meth.
01:57
And since it's what's called a substituent group or a branch, its ending is yl...
