Explain why has a magnetic moment value of 5.92 BM whereas has a value of only 1.74 BM.
[Fe(CN)6]3- involves d2sp3 hybridisation with one unpaired electron and [Fe(H2O)6]3+ involves sp3d2 hybridisation with five unpaired electrons. This difference is due to the presence of strong ligand CN– and weak ligand H2O in these complexes
