Identify the type of hybridization present in [ Ni ( CN )₄ ]²⁻ .
Options
- Asp ^3 ~d ^2
- Bdsp ^2
- Csp ^3
- Dd ^2 sp ^3
Correct answer
B. dsp ^2
Step-by-step solution
In [ Ni ( CN )₄ ]²⁻ , oxidation state of nickel is +2 . Valence shell electronic configuration of Ni ²⁺:[ Ar ] 3 ~d ^8 .3 ~d electrons are paired prior to the hybridisation and electronic configuration of Ni ²⁺ becomes: Four CN ⁻ ions donate their electron in four vacant dsp ^2 hybrid orbitals of Ni ²⁺ . Configuration after the complex formation becomes:
