The diatomic molecule OH exists in the gas phase and it plays an important part in combustion reactions and is a reactive oxidizing agent in polluted air. The bond length and bond energy are measured to be 97.06 pm and 424.7 kJ/mol respectively. The OH molecule is analogous to the HF molecule and that the bonding MOs result from the overlap of a p: orbital from oxygen and the 1s orbital of H and the O-H bond lies along the z-axis a) Draw pictures of the sigma bonding and antibonding molecular orbitals in OH. b) Which of the two MOs have the greater hydrogen 1s character? c) Can the 2p, orbital of O form MOs with the 1s orbital of H? Explain d) Knowing that only the 2p orbitals of oxygen interact significantly with the 1s orbital of H complete the MO energy-level diagram for OH e) Estimate the bond order for OH
