BITSAT Chemistry Question (2024) — Solution
Options
- A. s p^3 d and tetrahedral
- B. s p^3 and square planar
- C. s p^3 and tetrahedral
- D. d s p^2 and square planar
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.
