(a) Draw the molecular orbitals for the cyclopropenyl
Chapter 10, Problem 10P(choose chapter or problem)
(a) Draw the molecular orbitals for the cyclopropenyl case.
(Since there are three p orbitals, there must be three \(\text { MOs }\): one all-bonding \(\text { MO }\) and one degenerate pair of \(\text { MOs }\).)
(b) Draw an energy diagram for the cyclopropenyl \(\text { MOs }\). (The polygon rule is helpful.) Label each \(\text { MO }\) as bonding, nonbonding, or antibonding, and add the nonbonding line. Notice that it goes through the approximate average of the \(\text { MOs }\).
(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?
