Concept explainers
Interpretation: The number of unpaired electrons in the given complex ion
Concept introduction:
Origin of color: The coordination compound exhibit color due to d-d transitions. Absorption of wavelength from visible region which excites electron from the lower energy level to the higher energy level transmits the complementary color. Thus, the coordination compound looks colored.
Spectrochemical series: The list of ligands arranged in an ascending order of
Crystal field splitting: The energy gap between the splitting of d-orbitals of the metal ion in presence of ligands is known as the crystal field splitting
