We're given a bunch of different ir spectrum, and you're asked to identify the functional groups in each.
00:08
So in your first one, you have this very broad peak that's above and below 300 inverse centimeters.
00:20
And then you also have a peak around 1 ,700.
00:24
So this is the area for an alcohol.
00:27
This is an area for carbonyl.
00:28
And because this peak is so broad, it actually indicates.
00:32
That we have a corboxylic acid.
00:38
If you look at your second one, you have a sharp peak around 3 ,300.
00:49
You have some different peaks a little before 3 ,000, and you have the sharp peak here that's around 2 ,000.
01:05
So we have these peaks before 3 ,000.
01:09
These are for sp3 ,000.
01:10
Carbon hydrogen bending.
01:14
And this here tells us this is for an alkyne, and so is this.
01:22
And because we have both of these, it actually means we have a terminal alkyne...
