Hi in the given pair the first pair is not isomer to each other because molecular formula is not same.
00:13
This is the first condition for isomerism.
00:16
Here we can see that the number of carbon is 1 2 plus 3, 4, 6, 7, 8.
00:28
8 carbon is here and in this molecule 1, 2, 3, 4, 5, 6, 7.
00:34
So number of carbon is not same.
00:37
So we can say that molecular formula is not same.
00:39
So these are not isomer to each other.
00:42
And in the second pair, this pair is also not isomer to each other.
00:50
Because here is also molecular formula is not same...
