In this problem, we're given five different structures, and we're asked which matches the ir spectrum below.
00:06
So i'm going to go through and point out the major things we would see for each of these structures in an ir, and then we'll see what matches with what we have.
00:16
So here we have all sp3 carbons.
00:19
So we're just going to see peaks around 2 ,900, nothing greater than 3 ,000.
00:27
So this will be for your carbon hydrogen bonding for sp3 carbons.
00:31
Here, around 1600, we would expect double bonding for carbons.
00:42
We would have carbon hydrogen bonding for sp3, carbon that's at 2 ,900.
00:49
And usually around 30, 50, you'll see your sp2 carbon hydrogen bonding.
00:58
So that's going to be for the carbon and hydrogens here.

In our next one, our carbonyl will show up around 17...
