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