Unformatted text preview: the pi electrons in low energy molecular orbitals that extend over the sp2 hybridized ring atoms. These molecular orbitals involve overlap (in phase and out of phase) of the 2p orbitals on the sp2 hybridized ring atoms. 4. Aromaticity stabilizes ions and atoms in molecules exist in hybridization states that maximize aromatocit y . The lone pair on a ring atom will be in a 2p orbital if that leads to aromaticity . This explains why pyridine is much more basic than pyrrole. You will need to understand this before the next test....
