Hybridisation and geometry of [ Ni ( CN )₄ ]²⁻ are
Options
- As p^3 d and tetrahedral
- Bs p^3 and square planar
- Cs p^3 and tetrahedral
- Dd s p^2 and square planar
Correct answer
D. d s p^2 and square planar
Step-by-step solution
In [ Ni ( CN )₄ ]²⁻, Ni ²⁺=3 d^8 4 s^0 AsCN ⁻ is a strong ligand, pairing of electrons take place, Therefore, d s p^2 hybridisation gives square planar geometry.
