Which of the following will have maximum stabilization due to crystal field?
- \([Ti(H_2O)_6]^{3+}\)
- \([Co(H_2O)_6]^{2+}\)
- \([Co(CN)_6]^{–3}\)
- \([Cu(NH_3)_4]^{2+}\)
The Correct Option is C
Solution and Explanation
\(CN^–\) is the strongest ligand among the given complexes \(CFSE\) value for the \([Co(CN)_6]^{–3}\) complex will be highest as it has \(d^6\) configuration.
Hence, the correct option is (C): \([Co(CN)_6]^{–3}\)

Concepts Used:
Coordination Compounds
A coordination compound holds a central metal atom or ion surrounded by various oppositely charged ions or neutral molecules. These molecules or ions are re-bonded to the metal atom or ion by a coordinate bond.
Coordination entity:
A coordination entity composes of a central metal atom or ion bonded to a fixed number of ions or molecules.
Ligands:
A molecule, ion, or group which is bonded to the metal atom or ion in a complex or coordination compound by a coordinate bond is commonly called a ligand. It may be either neutral, positively, or negatively charged.
