The complex with highest magnitude of crystal field splitting energy ( ₀ ) is
Options
- A[ Cr ( OH ₂ )₆ ]³⁺
- B[ Ti ( OH ₂ )₆ ]³⁺
- C[ Fe ( OH ₂ )₆ ]³⁺
- D[ Mn ( OH ₂ )₆ ]³⁺
Correct answer
A. [ Cr ( OH ₂ )₆ ]³⁺
Step-by-step solution
smaller cations prefer coordinate bonding due to greater polarizing power. Ti ⁺³=67 pm radius, Cr ³⁺=62 pm radius Mn ⁺³=65 pm radius, Fe ⁺³=65 pm radius So, Cr ³⁺ has highest tendency to attract ligand.
