Question

The geometry arrangement of $CN$ groups around $Ni$ in $\left[Ni\right(CN{)}_4{]}^{2-}$ is:

• A. tetrahedron
• B. square planar
• C. trigonal bipyramid
• D. octahedron

Answer 1

The correct option is B square planar

In $\left[Ni\right(CN{)}_4{]}^{2-}$, $Ni$ has $ds{p}^2$ hybridisation. Its geometry is square planar.
