Question

Which of the following complex ion possesses $ds{p}^2$ hybridization ?

• A. ${\left[Ni{\left(CN\right)}_4\right]}^{2-}$
• B. $\left[Ni{\left(CO\right)}_4\right]$
• C. ${\left[NiC{l}_4\right]}^{2-}$
• D. $\left[Ni{\left(P{F}_3\right)}_4\right]$

Answer 1

Answer: (A)

${\left[Ni{\left(CN\right)}_4\right]}^{2-}$

Option (A) is correct.

${\left[Ni{\left(CN\right)}_4\right]}^{2-}$ involves $ds{p}^2$-hybridization, whereas $\left[Ni{\left(CO\right)}_4\right]$, ${\left[NiC{l}_4\right]}^{2-}$ and $\left[Ni{\left(P{F}_3\right)}_4\right]$ involve $s{p}^3$ hybridization.
