Question

In $[NiC{l}_4{]}^{2-}$ and $[Ni(CN{)}_4{]}^{2-}$ hybridization of $N{i}^{2+}$ is respectively

• A. $s{p}^3$ and $s{p}^3$
• B. $ds{p}^2$ and $d^{2}s{p}^3$
• C. $ds{p}^2$ and $s{p}^3$
• D. $s{p}^3$ and $ds{p}^2$

Answer 1

Answer: (D)

As $C{l}^{-}$ is a weak ligand. So, it gives high spin complexes and $C{N}^{-}$ is a strong ligand. So, here pairing will take place and will give low spin complexes.
