Hello students let's begin with this question.
00:03
This question is based upon the ir spectroscopy.
00:07
So this is one of the spectroscopy technique which is used to determine the functional group that is present in a compound.
00:18
So now if we see, if we see the firstly the options, the first one is the cyclopentanol, second one is the 1 -pentanol, then the third one is the 2 -pentanone and the fourth one is the 3 -pentanone.
00:39
Now here if we see the here let's draw their structures firstly.
00:44
So this is the cyclopentanol structure.
00:47
This will contains the ch and oh group.
00:50
Next is the 1 -pentanol.
00:52
Its structure is ch3, ch2, ch2, ch2, ch2 and oh.
00:59
Now the next one is the 2 -pentanone.
01:02
So its structure is this one.
01:05
So this is the 2 -pentanone.
01:06
It will contain the carbon double bond oxygen.
01:09
So it will does not contains the oh group...
