Question

Crystal field theory does not explain which of the following property of coordination compounds ?

• A. The covalent character of the bond between metal and the ligand
• B. Magnetic property
• C. Colour
• D. Structure of coordination compounds

Answer 1

The correct option is A The covalent character of the bond between metal and the ligand

Though the assumptions inherent in VBT and CFT are vastly different, the main difference lies in their description of the orbitals not occupied in the low spin states. VBT forbids their use as they are involved in forming hybrid orbitals, while they are involved in forming hybrid orbitals, while CFT strongly discourages their use as they are repelled by the ligands.

According to VBT, the bond between the metal and the ligand is covalent, while according to CFT it is purely ionic. The bond is now considered to have both ionic and covalent character unlike valence bond theory.
