Predict the number of unpaired electrons in the squar planar `[Pt(CN)_4]^(2-)` ion.

Text Solution

Verified by Experts

In square pianar .[P t(C N_4)]^2-. ion, .P t. is in .+2. oxidation state and has .d^8. configuration. For. square.plạnar shapc, the hybridization is .d s p^+.. Hence the unpaired electrons in . 5 dorbital pair up to make one d orbital empty for .^2 d s p^2. hybridisation. Thus there is qero unpaired electron. figure
