Predict the number of unpaired electrons in the square planar [Pt(CN)₄]^2- ion.

Ans :

In this complex, Pt is in the +2 state. It forms a square planar structure. This means that it undergoes dsp² hybridization. Now, the electronic configuration of Pd(+2) is 5d⁸.

CN^- being a strong field ligand causes the pairing of unpaired electrons. Hence, there are no unpaired electrons in
