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

Options

A. Octahedral, tetrahedral and square planar
B. Tetrahedral, square planar and octahedral
C. Square planar, tetrahedral and octahedral
D. Octahedral, square planar and octahedral

Answer

B

Explanation

`Ni^(2)+4Cl^(-)rarr[Ni(Cl)_(4)]^(2-)`, tetrahedral, `sp^(3)`, hybridization
`Ni^(2+)+4CN^(-)rarr[Ni(CN)_(4)]^(2-)`, square planar, `dsp^(2)` hybridization
`Ni^(2)+6H_(2)Orarr[Ni(H_(2)O)_(6)]^(2+)`, octahedral, `sp^(3)d^(2)` hybridization.
