Question

Among $\left[NiC{l}_2\right(PP{h}_3{)}_2],[Ni\left(DMG{)}_2\right]$ and $\left[Ni\right(CO{)}_4]$ complexes, the hybridisation states of $Ni$ atoms are respectively :

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

Answer 1

Answer: (B)

$s{p}^3,ds{p}^2,s{p}^3$

The nickel atom in the complexes $\left[NiC{l}_2\right(PP{h}_3{)}_2]$, $\left[Ni\right(DMG{)}_2]$ and $\left[Ni\right(CO{)}_4]$ undergoes $s{p}^3,ds{p}^2$ and $s{p}^3$ hybridization respectively to form tetrahedral, square planar and tetrahedral complexes.
