Okay, so we have a cyclic amine, and we need to find constitutional isomers of it.
00:10
What this means, in practical terms, is that we need to find a molecule that has five carbons, one nitrogen.
00:23
And then you'd think we'd have to count the hydrogens, but as long as the molecule we find has one double bond or one ring, could be a three -membered ring, five -membered ring, what have you.
00:41
It's guaranteed to have the correct number of hydrogens.
00:47
So really, we just need to find five carbons, one nitrogen, and then either a double bond or a ring.
00:53
So let's look at a, two, three, four, five, five carbons, a nitrogen, and it has a double bond.
01:02
So this is guaranteed to have the same molecular formula.
01:05
So a is a constitutional isomer.
01:09
Next, we can look at this molecule.
01:17
This is actually the same exact molecule.
01:19
It's just been rotated slightly...
