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, 10, 20², 201, 30², 171, 17² and the ground state of molecular nitrogen is 102, 10, 20, 20, 171, 30². Given that log, 20g, 30g and 17₁ are bonding orbitals while 10, 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. [2] [3]
