In this problem, we have indicated hydrogens on different compounds, and we're asked how many peaks it will split into.
00:08
So this is a question for proton and this is a type of spectroscopy that allows us to put together the different pieces of a molecule and figure out the structure from the data.
00:21
Now for splitting pattern, we use the n plus one rule, where n is going to be any neighboring hydrogens.
00:29
And one includes the hydrogen you're looking at and equivalent ones.
00:33
So in our first one here, we'll get this hydrogen.
00:36
This hydrogen is equivalent, so it's part of the one.
00:39
Then we have two neighboring hydrogens here and two here.
00:43
So you have four total.
00:45
So you're going to have five peaks.
00:49
In our next one, again, these are equivalent.
00:52
And we're next to a methyl group and a single hydrogen here...
