`[Fe(H_(2)O)_(6)]^(3+)` is strongly paramagnetic whereas `[Fe(CN)_(6)]^(3-)` is weakly paramagnetic Explain.

Text Solution

Verified by Experts

In both the complexes, `Fe is in +3` oxidation state with the configuration `3d^(5)` `CN^(-)` is a strong ligand. In its presence, 3d electrons pair up leaving only one unpaired electron. The hybridization is `d^(2)sp^(3-)` forming inner orbital complex. `H_(2)O` is a weak ligand. In its presence, 3d electrons do not pair up. The hybridization is `sp^(3)d^(2)` forming an outer orbital complex containing five unpaired electrons. Hence, it is strongly paramagnetic
