You can draw MO diagrams for the $\pi$ system of benzene without actually knowing that is it aromatic, and figure out from the diagrams that it is aromatic - which is the origin of Huckel's famous $(4n+2)$ rule... I mean, it's probably really just how you look at it. If you can get your hands on it, see Ian Fleming's Molecular Orbitals and Organic Chemical Reactions for a description. | |

| Oct 24, 2015 at 19:12 | comment | added | Martin - マーチン♦ | VB and MO will predict the same structure as the wave functions are essentially the same, if the description of complete. Differences do not carry any physical meaning and this is what the question is about. | |
