Explain on the basis of V.B, theory that [Ni(CN)_4]^(2-) ion with square planar structure is diamagnetic and the [NiCl_4]^2- ion with tetrahedral geometry is paramagnetic.

Assertion : [Ni(CN)_4]^(2-) is square planar and diamagnetic. Reason : It has no unpaired electrons due to presence of strong ligand.

[NiCl_4]^(2-) is paramagnetic while Ni(CO)_4 is diamagnetic though both are tetrahedral.Why?

Statement-1 : [Ni(CO)_4] has square planar geometry while [Ni(CN)_4]^(4-) has tetrahedral geometry. Statement-2 : Geometry of above complexes depends upon the nature of ligands attached.

Explain how the complexes of Nickel. [Ni(CN)_4]^(2-) and [Ni (CO)_4 ] have different structure, but do not differ In their magnetic behaviour. (Ni, Atomic No : 28).

Apart from tetrahedral geometry, another possible geometry for 'CH_4' is square planar with the four H atoms at the corners of the square and the Catom at the centre. Explain why 'CH_4' is not square planar.

Find the square root of the complex 3+4i .

[Cr(NH3)6]^3+ is paramagnetic while [Ni(CN)4]^2- is' diamagnetic. Explain why?

Assertion : [Fe(H_2O)_6]^(3+) is strongly paramagnetic whereas [Fe(CN)_6]^(3-) is weakly paramagnetic. Reason : H_2O is a weak field ligand and CN^(-) is a strong field ligand.
