Continue your studies in the central science: CHEM1102 available in semester 1, 2 and in Summer School
Bonding - MO theory
Learning outcomes - after studying this topic, you should be able to:
explain how electron sharing leads to lowering of electronic energy in terms of increasing the de Broglie wavelength. predict electronic configurations and bond orders for diatomic molecules, given a molecular orbital (MO) energy diagram predict relative binding energies and bond lengths from bond order recognise a bonding or antibonding orbital from the lobe representation recognize a σ orbital and a σ* orbital recognize a π orbital, a π orbital and a non-bonding orbital identify the valence electrons and orbitals in diatomic molecules distinguish between polar and apolar bonds in diatomic molecules and relate it to electron attraction of a nucleus (electronegativity) draw out ground state electronic configurations for molecules and molecular ions given their allowed energy levels calculate bond order from molecular electronic configurations explain the difference between paramagnetism and diamagnetism predict whether a molecule will be diamagnetic or paramagnetic from its orbital energy diagram recall the meaning of HOMO and LUMO and determine the lowest energy electronic transition
