Question

The coordination number of `Ni^(2+)` is 4.
`NiCl_(2) + KCN ("excess") rarr A ("cyano comples")`
`NiCl_(2) + conc. HCl ("excess") rarr B ("chloro complex")`
The hybridisation of A and B are
A. `dsp^(2), sp^(3)`
B. `sp^(3),sp^(3)`
C. `dsp^(2),dsp^(2)`
D. `sp^(3)d^(2),d^(2)sp^(3)`

Answer 1

Correct Answer - A
Hybridisation of Ni `K_(2)[Ni(CN)_(4)]` is `dsp^(2)` and in `K_(2)[Ni(CL_(4))]` is `sp^(3)`
