Right, the compounds that we're given, when we start to draw it originally, we see that it has a pentane chain.
00:10
So pentane is five carbons.
00:14
All right.
00:15
So we have a five carbon chain.
00:17
And when we look at those substituents, okay, we have, it says four ethyl.
00:23
So ethyl, remember, is two carbons with all hydrogens attached.
00:27
Okay, so hydrogens, hydrogen, hydrogen, hydrogen, hydrogen.
00:32
Then we have, two, three isopropyl.
00:37
Right.
00:37
So isopropyl is a three carbon chain with the carbon in the middle as the attached carbon.
00:45
Right.
00:46
And these all have the appropriate hydrogens as well.
00:49
Right.
00:50
Just shortcut.
00:51
Quick shortcut here.
00:53
Right.
00:54
Okay.
00:55
So that is our structure that we are given...
