Chemistry Draw the π-molecular orbitals of the cyclopentadienyl radical in terms of increasing energy.  Show clearly the locations of nodes and the different phases of the lobes.  Do not draw the molecular orbitals as a series of p-orbitals. Place the electrons into the orbitals as they would be in the electronic ground state.  Finally, using Frost’s circle, calculate the β-value for each of the π-molecular orbitals
