Question we talked for which of the following reaction which of the following statement are sure following is consistent with the higher spectrum of a product.
00:08
So you have carbon triple bond here and it's going to have the ch stretch around 3300 around 32 600 and then it's going to also have the carbon carbon triple bond stretch around 2200.
00:27
So the question is the option say it's absorption at 2150 should disappear, that's correct.
00:33
Absorption at 300 and 20150 should disappear.
00:37
That's also correct.
00:38
Absorption at 2250, she disappeared.
00:42
New absorption at 3 ,300 should appear.
00:45
That's wrong.
00:46
Absorption at 3 ,300 reciprocal web number and 2150 reciprocal wave number should disappear.
00:52
That's correct.
00:53
And new absorption at 1720, she appears.
00:56
So d is the correct answer because it's a touchy.
00:59
Everything so if the answer is d predict the product for the following reaction and explain how you we use higher spectroscopy to monitor the progress of a reaction so this is kind of a grid knot reaction so what's going to happen is that you are going to see so you are going to convert this c double one hole this add this ketone group to an harko ho.
01:34
So what we happen is you're changing the c -h -h -o -h.
01:41
So the option says absorption at 3200 to 3 ,600 reciprocal wave number, and 1720 should disappear, should appear.
01:55
So 1720 is actually the haco as the hard they hide or the c1 -o stretch, so that's wrong.
02:03
This should disappear.
02:07
Okay, let's keep going.
02:10
Absorption at 2250 should disappear.
02:13
There's nothing at 2250...
