Okay, so here we're trying to see how many constitutional isomers have this formula, c2h3of.
00:08
And the constitutional ismer is just another word for structural isomer.
00:12
So this is going to have the same formula, but the molecules or the atoms might be arranged a different way.
00:18
So first, i'm going to calculate my degrees of unsaturation, just so i know how many double bonds i might have, or race.
00:25
So to calculate that, i'll do the number of carbons, which is 2, times 2.
00:39
And then we add two to that.
00:42
And we're going to subtract the number of hydrogens and halogens.
00:46
So that's going to be four.
00:48
And we divide by two.
00:50
So that is 6 minus 4 divided by 2.
00:53
So this means we'll have one double bond in this system.
00:57
It could also be one ring, but we don't have enough atoms for that...
