Which among the following statements about [ Ni ( CN )₄ ]²⁻ is NOT true?
Options
- AIn this electron are paired prior to hybridization
- BOxidation state of Ni is +6
- CNi undergoes dsp ^2 hybridization
- DIt is a square planar complex
Correct answer
B. Oxidation state of Ni is +6
Step-by-step solution
[ Ni ( CN )₄ ]²⁻ Ni ²⁺ Oxidation state of Ni is +2 - CN ⁻ is strong field ligand. - Electrons are paired prior to hybridization. Ni ²⁺[ Ar ] 3 ~d ^8 - dsp ^2 hybridization and square planar complex.
