Vedclass · Answer

(B) The crystal field theory $(CFT)$ is an electrostatic model which considers the metal-ligand bond to be ionic arising purely from electrostatic interactions between the metal ion and the ligand.Ligands are treated as point charges in case of anions or point dipoles in case of neutral molecules.The theory is successful in explaining the formation,structures,colour,and magnetic properties of coordination compounds.However,it fails to explain the covalent character of metal-ligand bonding,as it assumes the bond is purely ionic.Therefore,statements $II, III,$ and $IV$ are correctly explained by $CFT$.

The crystal field theory is successful in explaining which of the following?
$I.$ Ligands as point charges;
$II.$ Formation and structures of complexes.
$III.$ Colour;
$IV.$ Magnetic properties;
$V.$ Covalent character of metal-ligand bonding.
