Explain the following giving reasons  (a) `[NiCI_(4)]^(2-)` is tetrahedral and paramagnetic whereas `[Ni(CN)_(4)]^(2-)` is square plannar and dimagnetic  (b) `[Fe(H_(2)O)_(6)]^(3+)` ion is more paramagnetic than `[Fe(CN)_(6)]^(3-)` ion  (c ) `Ni(CO)_(4)` is tetrahedral while `[Ni(CN)_(4)]^(2-)` ion is square planar  (d) `[Co(F_(6))]^(3-)` is a high spin complex whereas `[Co(CN)_(6)]^(3-)` ion is a low spin complex .
