How do these molecular orbitals differ from those obtained from linear combinations of the 2py atomic orbitals? (The 2p, orbitals are also oriented perpendicular not only to the bonding axis but also to the 2pz orbitals.) Drag the terms on the left to the appropriate blanks on the right to complete the sentences. Reset Help 90° The difference between the 2p, and the 2pz atomic orbitals is a rotation about the 180° internuclear axis. Consequently, the difference between the resulting MOs is a 45° rotation about the internuclear axis. The energies and the names of the bonding and antibonding MOs obtained from the combination of the 2py atomic orbitals are those obtained from the combination of the 2pz atomic orbitals.
