Hello friends.
00:01
So our question is use the following figures to answer the question.
00:05
So basically we are given four options and these four options we are given the structure of four compounds.
00:11
And we have to tell which molecule shown has a carbonyl function that is co function in the form of a ketone.
00:20
So we have to tell in which of these compound is a ketone.
00:25
They only ask us which of these compound is a ketone.
00:30
Contains a ketone group with carbon oil.
00:32
So basically r -c -o -r.
00:36
This is the structure of ketone.
00:39
This is keto.
00:41
So in chemistry, a ketone is a functional group which is the structure of r2 -c -o, where r is a variety of carbon -containing substituents.
00:52
It may be any of the functional groups which have displaced carbon.
00:57
So talking about the option number one, option number a, we see that here it is present carbonyl and on seeing this, this ch3 is r.
01:10
This is our functional group here.
01:12
So it has a structure of rcoh...
