Question

In which of the following complex ions the central metal ion is $d{p}^2$ hybridized?

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

Answer 1

The correct option is D $\left[Ni\right(CN{)}_4{]}^{-2}$

$N{i}^{+2}\to 3d^{8}4s^{\circ }4P^{\circ }$

$C\overline{N}$, strong field ligand regroups the electrons

$ds{p}^2$ hybridization
