Textbook Question
Chapter 16.8A, Problem 16.10P
- a. Draw the molecular orbitals for the cyclopropenyl case.
(Because there are three p orbitals, there must be three MOs one all-bonding MO and one degenerate pair of MOs.)
- b. Draw an energy diagram for the cyclopropenyl MOs. (The polygon rule is helpful.) Label each MO as bonding, nonbonding, or antibonding, and add the nonbonding line. Notice that it goes through the approximate average of the MOs.
- c. Add electrons to your energy diagram to show the configuration of the cyclopropenyl cation and the cyclopropenyl anion. Which is
aromatic and which is antiaromatic?
