Select an incorrect statement regarding the Crystal Field Theory(CFT).
According to CFT, the anionic ligands should exert the greatest splitting effect
CFT does not take into account the covalent nature of bonding between the ligand and the central atom
CFT does not explain the bonding in metal carbonyls
CFT is not successful in explaining the formation, structures, colour and magnetic properties of coordination compounds.
As we have learnt,
The crystal field theory is successful in explaining the formation, structures, colour and magnetic properties of coordination compounds.
From the assumptions of CFT that the ligands are point charges, it follows that anionic ligands should exert the greatest splitting effect. The anionic ligands actually are found at the low end of the spectrochemical series.
CFT does not take into account the covalent character of bonding between the ligand and the central atom and also does not explain the synergic bonding in metal carbonyls.
Hence, the statement given in Option (4) is incorrect
Therefore, the answer is Option (4)
