II.It has eight d electrons.
III.It is tetrahedral.
IV.It is square planar.
V.It is strong field.
VI.It is weak field.

Question

Quizplus · Accepted Answer

Ni(CN)4^2- is diamagnetic because it has eight d electrons (Ni^2+ in a d^8 configuration), adopts a square planar geometry (common for d^8 complexes), and involves strong field ligands like CN^-, which leads to pairing of electrons in the d orbitals.
