00:02
All right, so here we're looking at the structure.
00:04
We're trying to predict the splitting pattern of the three hydrogens on the screen.
00:10
So in order to determine splitting pattern, we need to find out how many hydrogens there are on neighboring carbons to whichever hydrogen we're looking at.
00:21
And in order to find out the splitting, we're going to follow the m plus 1 rule.
00:25
So if there is one hydrogen on an adjacent carbon, then n plus 1 says we'll do 1 plus 1.
00:32
Which will give us two peaks or doublet.
00:37
So let's go ahead and look and see what we have on the structure.
00:40
So for ha, it's on this carbon and the adjacent carbon next to it is this one here.
00:49
And so on that carbon, only one hydrogen is shown, but we know there are two.
00:55
It's a ch2.
00:57
So because there's two neighbors, ha will follow the m plus 1 rule.
01:04
2 plus 1 is 3.
01:07
So ha will be a a triplet.
01:16
All right, next we can look at hb.
01:18
So on hb, we have two carbons adjacent...
