Geometrical shapes of the complexes formed by the reaction of $Ni^{2 +}$ with $Cl^{-}, CN^{-}$ and $H_{2} O$ respectively, are -

Answer:

Solution:

The geometry of Ni²⁺ complexes depends on the ligand and its field strength.

1. With Cl⁻ (weak field ligand), Ni²⁺ forms tetrahedral complexes, e.g., $[N i C l_{4}]^{2 -}$ .

2. With CN⁻ (strong field ligand), Ni²⁺ forms square planar complexes, e.g., $[N i (CN)_{4}]^{2 -}$ .

3. With H₂O (weak field ligand), Ni²⁺ forms octahedral complexes, e.g., $[N i (H_{2} O)_{6}]^{2 +}$ .

Therefore, the shapes are tetrahedral, square planar, and octahedral, respectively.
