Among the following, the square planar geometry is exhibited by:

A
${CdCl}_{4}^{2 -}$
B
$Zn (CN)_{4}^{2 -}$
Correct answer
C
${PdCl}_{4}^{2 -}$
D
$Cu (CN)_{4}^{3 -}$

Solution

\begin{matrix} Complex & Shape & Hybridisation \\ {[{CdCl}_{4}]}^{2 -} & Tetrahedral & {sp}^{3} \\ {[Zn (CN)_{4}]}^{2 -} & Tetrahedral & {sp}^{3} \\ {[{PdCl}_{4}]}^{2 -} & Square Planar & {dsp}^{2} \\ {[Cu (CN)_{4}]}^{3 -} & Tetrahedral & {sp}^{2} \end{matrix}

Hence, the correct answer is option: 'C'.
