Which among the following statements about [ Ni ( CN )₄ ]²⁻ is NOT true?

Options

  1. AIn this electron are paired prior to hybridization
  2. BOxidation state of Ni is +6
  3. CNi undergoes dsp ^2 hybridization
  4. 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.
