Assertion : [Fe(CN)_(6)]^(3-) ion shows magnetic moment corresponding to two unpaired electrons. Reason : Because it has d^(2)sp^(3) type hybridisation.

Answer»


Solution :Correct assertion. `[FE(CN)_(6)]^(3-)` has `Fe^(3+) (3d^(5)=3d^(1)3d^(1)3d^(1)3d^(1)3d^(1))`. In PRESENCE of `CN^(-)`, electron PAIR upto give `3d^(2)3d^(2)3d^(1)3d^(0)3d^(0)`. HYBRIDIZATION is `d^(2)sp^(3)`. Thus, it will have magnetic moment corresponding to one electron.
