Answer» Solution :`[MnCl_(4)]^(2-)` Electronic configuration of `Mn` atom Electronic configuration of `Mn^(2+)` ion Hybridisation and formation of `[MnCl_(4)]^(2-)` complex `Cl^(-)` isweak field ligand no electrons pairing occurs. `sp^(3)` hybridisation It has `5` unpaired electrons. Hence paramagnetic Magentic moment, `mu_(s)=sqrt(n(n+2))BM` `n=5` `mu_(s)=sqrt(5(5+2))=sqrt(5(7))` `=sqrt((35))=5.9BM` It has TETRAHEDRAL geometry.
