The CN of Ni^(+2)=4 NiCl_(2)+KCN_("excess")toA (cyano complex) NiCl_(2)+conc.KCl_("(excess)")toB (Chloro complex) The hybridisation of A and B are

Answer»

`dsp^(2),sp^(3L)`
`sp^(3),sp^(3)`
`dsp^(2), dsp^(2)`
`sp^(3)d^(2)` both

Solution :(A) Hybridisation of NI in `K_(2)[Ni(CN)_(4)]` is `dsp^(2)`.
(B) Hybridisation of Ni in `K_(2)[Ni(CN)_(4)]` is `sp^(3)`.
