Sketch the bonding and antibonding molecular orbitals that result from linear combinations of the 2p_z atomic orbitals in a homonuclear diatomic molecule. (The 2p_z orbitals are those whose lobes are oriented perpendicular to the bonding axis.)

How do these molecular orbitals differ from those obtained from linear combinations of the 2p_y atomic orbitals? (The 2p_y orbitals are also oriented perpendicular to the bonding axis but are also perpendicular to the 2p_z orbitals.)
