alleryWhat is the geometry of [Ni(CN)4]²⁻?
ASquare planar
BTrigonal planar
COctahedral
DTetrahedral
Answer & Solution
Correct answer: A. Square planar
CN = 4 with strong-field ligand (CN⁻) and Ni²⁺ (d⁸): typically dsp² hybridization → square planar.
(Compare with [NiCl4]²⁻ which is tetrahedral with weaker-field Cl⁻.)
