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?
