Question 9 (a) In the LCAO approximation, which of the following three pairs of atomic orbitals, centred on different atoms in a diatomic molecule, produce o molecular orbitals? (1so, 1so), (2po, 2po), (2P1, 2P1). (b) The ground state of molecular oxygen is 102, 102, 202, 202, 30², 1₁, 1² and the ground state of molecular nitrogen is 102, 102, 202, 202, 14, 30². Given that 10g, 20g, 30g and 17u are bonding orbitals while 10u, 20 and 17g are antibonding orbitals, what are the formal bond orders of the N₂ and O2 molecules? Hence or otherwise explain which molecule has the lower dissociation energy.
