Which of the following statement is not correct?[Ni(CN)4]−2 and [Ni(CO)4] have the same magnetic moment[NiCl4]−2 and [PtCl4]−2 have different shape.Hybrid state of Co in [Co(Ox)3]−3 is sp3 d2In brown-ring complex [Fe(H2O)5NO]SO4 oxidation state of Fe is +1

Assertion A : In the complex Ni(CO)4 and Fe(CO)5, the metals have zero oxidation state.Reason R : Low oxidation states are found when a complex has ligands capable of π-donor character in addition to the σ-bonding.In the light of the above statements, choose the most appropriate answer from the options given belowA is correct but R is not correctA is not correct but R is correctBoth A and R are correct but R is NOT the correct explanation of ABoth A and R are correct and R is the correct explanation of A

Write oxidation state of Ni in [Ni(CO)4 ]

The complex [Ni(CN)4]2- is diamagnetic while [NiCl4]2- is paramagnetic and hastwo unpaired electrons. Explain these observations using the Valence BondTheory (VBT) and deduce the geometries of the two complexes

The hybridisation of Ni in Ni(CO)4

The correct statements from following are:A. The strength of anionic ligands can be explained by crystal field theory.B. Valence bond theory does not give a quantitative interpretation of kinetic stability of coordination compounds.C. The hybridization involved in formation of [Ni(CN)4]2−[Ni(CN)4]2− complex is dsp 22.D. The number of possible isomer(s) of cis- [PtCl2(en)2]2+[PtCl2(en)2]2+ is one
