11. The s-orbital ( lone pair ) is inert and the vacant p-orbital is very reactive. 12. It is a matter of taste whether one includes the lone pair in a drawing. 13. However, not all non-bonding pairs of electrons are considered by chemists to be lone pairs . 14. Is a lone pair more real than an orbital? 15. :Btw, carbon has no lone pairs in graphite. 16. Non-bonding orbitals are the equivalent in molecular orbital theory of the lone pairs in Lewis structures. 17. The lone pairs of electrons on the oxygen of the hydroxyl group also makes alcohols nucleophiles. 18. :: Carbon doesn't hold lone pairs very well. 19. An additional deprotonation by a alpha-beta unsaturation and pushing a lone pair onto the aldimine nitrogen. 20. All the interaction sites are centered on the atoms; there are no " lone pairs ".
