So drawn here, i've got on the left, just cyclohexane.
00:04
And on the right, i've got benzene, which is an aromatic compound.
00:08
And you can see that the biggest difference between these two structures is the presence of those double bonds in the benzene.
00:15
So in other words, all aromatic compounds use pi orbitals and use pie bonding.
00:21
That greatly increases their stability, which is why most aromatics are incredibly stable.
00:27
So in terms of 3d structure, this also has a pretty substantial effect.
00:33
Because with cyclohexane on the left, now you can kind of imagine that these molecules are going to be kind of up and down.
00:41
It's not going to be a perfectly flat surface...
