Draw just the bonding -MO’s for the cycloheptatrienyl cation. Draw the energy diagram to show the relative energies of all the MO’s, and show which orbitals the electrons would occupy in the ground state. Predict whether this ion is aromatic, antiaromatic, or nonaromatic.
Because all of the six electrons are below the zero energy line, this electronic configuration is aromatic. All of the electrons are in bonding molecular orbitals.
