Question

02. Which statement most correctly describes crystal field theory for a d block complex
of unspecified geometry?
a) The theory considers covalent interactions between a metal centre and the surrounding
ligands
b) The theory considers electrostatic interactions between a metal ion and the
surrounding ligands which are taken to be point charges
c) The theory rationalizes the non-degeneracy of the metal d orbitals by considering the
electrostatic repulsions between point charge ligands and electrons in the
metal d orbitals​

Answer 1

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 dipoles in case of neutral molecules.
