Magnetic moment of [Ni(CN)4]2− is zero but that of [Ni(H2O)4]2+ is 2.83 B.M. It is because of –
A
CN− is a strong ligand making two unpaired electrons in Ni2+ to pair up, while in [Ni(H2O)4]2+ two electrons remain unpaired as H2O is a weak ligand
B
different oxidation state of Ni in two complexes
C
both (A) and (B)
D
none of the above
