00:01
So we're supposed to give the iupac name of this, of each of these structures.
00:07
We have to check the longest chain of carbon atoms.
00:10
So here we have 1, 2, 3, 4, 5, 6, 7, 8.
00:17
I'm not sure if there's any other, you know, longer chain.
00:24
Don't think so.
00:25
So 1, 2, 3, 4, 5, 6, 1, 2, 1, 2, 3, 4, 5, 6, 7.
00:35
Now, there's no longer chain.
00:36
The longest chain is 8, which means that this is a substituent and this is a substituent and this is a substituent.
00:46
So i'm going to circle the substituent with another color.
00:49
This is a substituent.
00:50
Now it's a substituent.
00:51
It's a substituent.
00:52
This is your isopropyl.
00:56
This is a propyl substituent, but it's isopropyl.
01:01
It's an isopropyl substituent, and those are methyl groups.
01:06
So we need to check which numbering is going to be easier.
01:11
If we number the other way around, let me just show what we have there.
01:16
This, them, that, and down.
01:24
Down, down, down, down, 1, 2, 3, 4, 5, 6, 7, 8.
01:29
So if you number, and then we have the substituent here, we have a substituent here, and here.
01:42
So if we number this way, 1, 2, 3, 4, 5, 6, 7, 8, 8.
01:50
My substituents are on columns 5, 6, and 4.
01:57
If you number the other way around, 1, 2, 3, 4, 5, 6, 7, and 8.
02:06
Our substituents are on 3, 4, and 5.
02:11
So we're going to pick that, the smaller one.
02:13
So the name of that should be 3, 4.
02:20
So you're sorry, the propyl should come first because alphabetical order...
