Among $\left[\mathrm{Ni}(\mathrm{CO})_4\right],\left[\mathrm{Ni}(\mathrm{CN})_4\right]^{2-}\left[\mathrm{NiCl}_4\right]^{2-}$ species the hybridisation states at the $\mathrm{Ni}$ atom are respectively: [Atomic number of $\mathrm{Ni}=28$ ]
  1. $s p^3, d s p^3, d s p^2$
  2. $s p^3, d s p^2, s p^3$
  3. $s p^3, s p^3, d s p^2$
  4. $d s p^2, s p^3, s p^3$

Solution

Related Theory The hybridization of the atomic orbitals of the central metal atom of inner orbital complex involves inner shell $d$ orbitals whereas the hybridization of the atomic orbitals of the central metal atom of outer orbital complex involves outermost shell $d$.
