Concept explainers
Interpretation:
The oxidation number and number of unpaired electrons in the given coordination compounds are to be determined.
Concept introduction:
The oxidation number ofa metal atom is equal to the charge on the metal atom.
In low spin, the crystal filed splitting is large. So, the lower orbitals are filled completely before the upper orbitals are populated.
Ligands that cause a high degree of splitting among the
The weak-field ligand makes valence electrons enter into separate
Spectrochemical series:
These ligands are arranged in order of increasing value of
Strong field ligands form low spin complex.
The halide and hydroxide ion are weak field ligands because they cause less splitting of the d-orbital
Weak field ligands form high spin complex.
