Column-III

(a)

(i) Inner orbital complex

(P)Total possible isomers = 3

(b)

(ii) Low spin complex

(Q)Total possible isomers = 6

(c)

(iii) Outer orbital complex

(R) Total possible isomers = 8

(d)

(iv) High spin complex

(S) Total possible isomers = 10

.

Select INCORRECT combination is :

Options:

Answer:
D
Solution:

Central Atom & Ligand: In K₂[Ni(CN)₄] (c), the central metal ion is Ni²⁺ ( configuration), and CN⁻ is a strong-field ligand.

 

Hybridization: The strong field ligand forces electron pairing, resulting in a square-planar, low-spin inner-orbital complex with dsp² hybridization.

 

Isomerism: Being a square-planar complex of the type , it does not exhibit geometrical or optical isomerism, meaning the total possible isomers is not 8 (r).

 

Conclusion: Since combination (c)-(i)-(r) contains an incorrect number of isomers, option (D) is the correct choice.
