Chemistry - Coordination Chemistry Question with Solution | TestHub

Concepts: Crystal Field Theory, Ligand field strength, d-electron count, hybridization.

Explanation:

For ${\left[{\mathrm{NiCl}}_4\right]}^{2-}$, Ni is in +2 oxidation state ($d^8$). Cl⁻ is a weak field ligand, leading to $s{p}^3$ hybridization and a tetrahedral geometry.
