In this problem, we're given an ir spectrum and we're asked which structure we're also given could match.
00:14
So first, i want to go through those structures that we're given and point out key functional groups that would show up and we'll talk about where they should show up.
00:26
And then once we've done that, we'll look at our spectrum and we'll determine.
00:33
Which matches up with that.
00:54
So if we start with our first structure here, we have a triple bond between carbons, so it show up around 2100.
01:04
Our sp carbon hydrogen bonding would show up around 3 ,300.
01:10
And our alcohol would show up around 3 ,300 as well, but it would be a very broad peak.
01:17
Our next one, we're going to have the same first two peaks.
01:25
But there's no alcohol.
01:31
Then here we have a carbonyl, so this will show up around 1 ,700, and a carbonyl acid alcohol would show up in a very broad range here...
