Unformatted text preview: Internuclear approach is along the z axis z Resulting Sigma Bonding MO ( σ 2p ) Sigma Bond MOs Between P Orbitals Note where the nuclei are, and this MO has two nodes 2p z 2p z orbital overlap is inphase z 2p z + 2p z atomic orbitals Overlap is outofphase Sigma Antibond Formation ( σ 2p * ) Resulting σ 2p * antibonding molecular orbital 2p + 2p Wave functions that are outofphase interact to give antibonding molecular orbitals. Here, we show the interaction of two 2p z atomic orbitals (2p z + 2p z ) to form the σ 2p * MO. Z axis Z Z σ 2p * • There are three pairs of p orbitals and thus six MOs, a s, s*, 2 x p and 2 x p* 6 p AOs Combine to Make 6 MOs The 2 bonding π 2p orbitals are degenerate (same energy) Why? The 2 antibonding π * 2p orbitals are degenerate (same energy) Why? The Expected MO Diagram for B 2...
