We're first looking at this reaction here, where we're going from an alcohol to an aldehyde.
00:11
So our functional groups in ir are going to be this one and this one.
00:18
So for an alcohol, you'd have peak somewhere around 3 ,200 to 3 ,500, a broad peak like this.
00:30
And the reaction will be complete when this goes away in your ir.
00:34
And in this place you have the carbonyl so that's going to be around 1715 and really that can be anywhere from 1670 to 1760 roughly and also the carbon hydrogen bond here you will see that at 2700 and 2 800 inverse centimeters too as something like this and your carbonyl will be a sharp strong peak.
01:10
So you want the appearance of all of this with the disappearance of this to show your reaction is complete.
01:17
And then you're told that you have a structure with major peaks at 3070 and 1660 in your spectrum.
01:31
So right above 3 ,000, you're going to find sp2 carbon hydrogen bonding...
