Which of the following has square planar geometry?
Options
- A[ PtCl ₄ ]²⁻
- B[ NiCl ₄ ]²⁻
- C[ ZnCl ₄ ]²⁻
- D[ CoCl ₄ ]²⁻
Correct answer
A. [ PtCl ₄ ]²⁻
Step-by-step solution
[ PtCl ₄ ]²⁻ has square planar geometry. Pt : 5 d⁹ 6 s¹ Two electrons are removed from 5 d shell and 6 s shell. So, hybridisation takes place is d s p² i.e. square planar geometry.
