Okay, so this problem has two parts.
00:05
The first asks you if this, each of these following compounds are cis and trans, or are able to form cis and trans isomers, and if so, you want to draw them out.
00:18
So when you're thinking about cis and trans isomers, what you want to look at is you want to look at the two carbons on the double bond.
00:26
And you want to make sure that these two carbons are attached to two different roots.
00:32
So if we look at this carbon, and this carbon, you see that this carbon on the left is attached to a hydrogen and attached to a methyl group.
00:43
On the right, you have this carbon is attached to a hydrogen and to an ethical group.
00:49
So yes, this compound is able to form your cis and trans isomers.
00:55
And so if we draw them out, so we can have ch3, ch2, ch3, and, and so you want to keep one the same, 2, c ,h, 4.
01:21
So when you're talking about cis and trans, you're talking about the location of the hydrogen atoms.
01:26
So if your hydrogen atoms are on the same side of the double bond, they are cis.
01:32
If the hydrogenate atoms are on the opposite side, they are trans.
01:43
Look at the second one.
01:47
Okay.
01:47
So in order to figure out if it's cis or trans, we want to look at this carbon and this carbon...
