Question

Match the geometry (given in column A) with the complexes (given in column B).

Answer 1

(A) Octahedral geometry is shown by the complex $\left[Fe\right(CN{)}_6{]}^{4-}$. The central iron atom undergoes $d^{2}s{p}^3$ hybridization. It results in outer orbital complex or high spin complex.

(B) Square planar geometry is shown by the complex $\left[Ni\right(CN{)}_4{]}^{2-}$ due to $ds{p}^2$ hybridization.

(C) Tetrahedral geometry is shown by the complex$\left[Ni\right(CO{)}_4]$ due to $s{p}^3$ hybridisation.
