When crystals of CuSO4 . 4NH3 are dissolved in water, there is hardly any evidence for the presence of Cu2+ ions or ammonia molecules. A new ion [Cu(NH3)4]2+ is furnished in which ammonia molecules are directly linked with the metal ion. Similarly, aqueous solution of Fe(CN)2 .4KCNdoes not give tests of Fe2+ and CN- ions but give test for new ion [Fe(CN)6]4- called ferrocyanide ion.
Q. 
The hybridisation, geometry and magnetic property of [Fe(CN)6]4- are
  • a)
    d2sp3, octahedral, diamagneti
  • b)
    d2sp3, octahedral, paramagnetic
  • c)
    sp3d2, octahedral, diamagnetic
  • d)
    sp3d2, octahedral, paramagnetic

Hybridisation, Geometry and Magnetic Property of [Fe(CN)6]4-

Hybridisation:
The central metal ion Fe2+ has 6 ligands around it which include 6 cyanide ions (CN-) in [Fe(CN)6]4-. The hybridisation of the metal ion depends on the number of ligands and the type of ligands present around it. In this case, the hybridisation of Fe2+ ion in [Fe(CN)6]4- is dsp2.

Geometry:
The geometry of the complex ion is octahedral. The six ligands occupy the vertices of an octahedron and the metal ion occupies the center.

Magnetic Property:
The magnetic property of a complex ion depends on the number of unpaired electrons in the metal ion. In this case, Fe2+ ion has four unpaired electrons. Due to the presence of unpaired electrons, [Fe(CN)6]4- is paramagnetic in nature.

Therefore, the correct option is (a) d2sp3, octahedral, diamagnetic.
