In this problem, we start with a carbocation here, and we want to show our two resonant structures.
00:12
So we have resonant structure a, b, and c.
00:16
So to get to b, we want to only move one pair of electrons.
00:22
So remember that when a carbon has a positive charge, that means it has three bonds, and then an empty orbital that electrons can go into.
00:32
So if we have high electrons in our double bond, they can drop in here.
00:38
So when we do that, our first cyclohexene ring is the same.
00:44
But now we have a double bond here.
00:47
And what you can't neglect is that over here you have a plus one charge.
00:51
And if you think about your carbon here, it just lost electrons.
00:58
Lost a pair...
