JEE Mains · Chemistry · STD 12 - 5. Co-ordination chemistry
The complex with highest magnitude of crystal field splitting energy \(\left(\Delta_0\right)\) is
- A \(\left[ Cr \left( OH _2\right)_6\right]^{3+}\)
- B \(\left[ Ti \left( OH _2\right)_6\right]^{3+}\)
- C \(\left[ Fe \left( OH _2\right)_6\right]^{3+}\)
- D \(\left[ Mn \left( OH _2\right)_6\right]^{3+}\)
Answer & Solution
Correct Answer
(A) \(\left[ Cr \left( OH _2\right)_6\right]^{3+}\)
Step-by-step Solution
Detailed explanation
\(Ti ^{+3}=67\,pm\) 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.
