Options:
Answer:
Solution:
(P) : Ni²⁺ is d⁸; CN⁻ is a strong-field ligand, giving dsp² square planar, diamagnetic, and no geometrical/optical isomerism. The given properties are correct.
(Q) : Contains a cationic and anionic complex and shows coordination isomerism. The given properties are correct.
(R) : Ni²⁺ (d⁸) with weak-field F⁻ forms sp³d² octahedral, paramagnetic complex. The given properties are correct.
(S) is an octahedral complex of type , which shows fac–mer geometrical isomerism but does not show optical isomerism. Hence, the table entry is incorrect.
Answer: (D) (S)
