Geometrical shapes of the complex formed...

Geometrical shapes of the complex formed by the reaction of `Ni^(2+)` with `Cl^(Θ),CN^(Θ)` and `H_(2)O` are :

A

Octahedral, tetrahedral and square planar

B

Tetrahedral, square planar and octahedral

C

Square planar, tetrahedral and octahedral

D

Octahedral, square planar and tetrahedral

Text Solution

Verified by Experts

The correct Answer is:
B
`Ni^(+2) + 4Cl^(-) to [NiCl_4]^(2-)`
`[NiCl_4]^2 = 3d^8` configuration with Nickel in +2 Oxidation state. ` Cl^-` being weak field ligand does not compel for pairing of electrons.
