Question
The colour of a complex compound is due to:
✓
Answer
- Promotion of 3d-electrons of the central atom/ion to d-orbitals.
The colour of a complex compound is due to promotion of 3d-electrons of the central atom/ion to d-orbitals..
The colour of the complex compound is due to d−d electronic transition.The d-orbitals of a free transition metal atom or ion are degenerate (all have the same energy.)
When transition metals form coordination complexes, the d-orbitals of the metal interact with the electron cloud of the ligands in such a manner that the d-orbitals become non-degenerate (not all having the same energy).
