Give the theory of crystal field. |
|
Answer» Crystal field theory: 1. The metal-ligand bond is ionic arising purely from electrostatic interactions between the metal ion and the ligand. 2. Ligands are treated as point charges or dipoles in case of anions and neutral molecules. 3. In an isolated gaseous metal atom or ion the five d-orbitals are degenerate. 4. Degeneracy is maintained if a spherically symmetrical field of negative charges surrounds the metal /ion. 5. In a complex the negative field becomes asymmetrical and results in splitting of the d-orbitals. |
