Ligand Field Theory LFT in conjunction with the Molecular Or

Ligand Field Theory (LFT) in conjunction with the Molecular Orbital Theory (MOT):

t_2g in LFT corresponds to                                                                                  

e_g in LFT corresponds to

t_2gbonding in MOT

t_2gnonbonding in MOT

t_2gantibonding in MOT

e_gbonding in MOT

e_gnonbonding in MOT

e_gantibonding in MOT

Solution

t2g in LFT corresponds to - t2g nonbonding in MOT (option B)

eg in LFT corresponds to - eg antibonding in MOT (option F)

In the case of octahedral complexes, when we examine its MO diagram we find that the electrons initially present in the d-orbitals of the metal will enter into t2 nonbonding and eg antibonding (eg*) molecular orbitals and the difference in energy between the t2g nonbonding and eg* orbitals corresponds to ligand field stabilisation energy (LFSE).
