Classify O2 and N2 as either paramagnetic or diamagnetic. Explain your answer by completing the orbitals in the given MO energy level diagrams above and referring to the electronic structure of these two molecules.

In the construction of the molecular orbital diagram of a polyatomic molecule (SF6), 12 valence electrons are used to occupy 10 MO; account for the origin of the 12 electrons and the 10 MOs

Assuming the polyatomic molecule SF6 and its cationic specie SF6+ were given, use molecular orbital theory to establish their ground state electronic configuration

Describe the bonding in both the superoxide ion (O2-) and the peroxide ion (O22-) in terms of molecular orbital theory, and compare their bond order to that of O2

Using specific examples of a homonuclear and heteronuclear diatomic molecule, highlight the differences in their MO energy level diagrams

For early period homonuclear diatomic molecules, the 2π orbitals are lower in energy than the 2σ orbital. However, for late period homonuclear diatomic molecules, the reverse is true. Explain why this is so

A Copper(II) octahedral complex shows 4 bonds of length 240 pm and 2 bonds of length 318 pm. Explain this observation with the help of a proper diagram.

In the formation of CO, the 2s orbital from C and 2p orbital from O could also participate in the formation of σ molecular orbital. Explain why this is possible?
