In this problem, we're looking at a proton and a mark question.
00:05
And here we're asked where we would find a triplet.
00:09
So remember that our splitting patterns are from the n plus 1 rule, where n is the number of neighboring hydrogens.
00:18
So if we look at our first option, athena, you'll notice that we have symmetry through here, and these hydrogens are identical.
00:30
And because of that, we call them chemically equivalent, and they don't split with each other.
00:35
So we're not going to see splitting here.
00:41
If we look at ethane, now we just have a single bondage in carbons.
00:47
But again, all of our hydrogens are equivalent, so we're not going to see splitting here.
00:54
If you look at bromalethane, now we have br, ch2, ch3.
01:00
Our hydrogens are no longer equivalent.
01:04
So these hydrogens have three neighbors...
