The formation of coordination complex compounds formed by transition metals is explained by?
Correct answer: D. Both A and B
- A. Ligand field theory
- B. Crystal field theory
- C. Molecular orbital theory
- D. Both A and B
Explanation
Option C : In molecular orbital theory, electrons in a molecule are not assigned to individual chemical bonds between atoms but are treated as moving under the influence of the atomic nuclei in the whole moleculeOption : D Ligand field theory (LFT) describes the bonding, orbital arrangement, and other characteristics of coordination complexes. It represents an application of molecular orbital theory to transition metal complexes. Crystal field theory (CFT) describes the breaking of orbital degeneracy in transition metal complexes due to the presence of ligands. CFT qualitatively describes the strength of the metal-ligand bonds. Based on the strength of the metal-ligand bonds, the energy of the system is altered.

About Transition Elements
Transition elements are identified by their partially filled d subshells in atoms or common ions. The topic covers the electronic structure of d-block elements, including the filling order of 4s and 3d orbitals, variable oxidation states and the distinction between transition elements and elements with completely filled d subshells.
