      A simple pictorial method using HOMO, LUMO, and LUMO+1 of azulene coupled with interaction between the electrons in the singly occupied orbitals is introduced to show how the S2-S0 energy gap relative to the S1-S0 gap can be changed by a choice of ...

      An analogy that may be useful in the classroom is described. The changes that occur in typical simple SN1 and SN2 reactions are compared to the metamorphoses undergone by caterpillars and tadpoles, respectively.
