Predict the order of Δ ∘ for the following compounds I M n H 2 O 6 2 + I I M n C N 2 H 2 O 4 I I I M n C N 4 H 2 O 2 2 -
Options
- AΔ ∘ I < Δ ∘ I I < Δ ∘ I I I
- BΔ ∘ I I < Δ ∘ I < Δ ∘ I I I
- CΔ ∘ I I I < Δ ∘ I I < Δ ∘ I
- DΔ ∘ I < Δ ∘ I I I < Δ ∘ I I
Correct answer
A. Δ ∘ I < Δ ∘ I I < Δ ∘ I I I
Step-by-step solution
C N - is a strong field ligand so greater the number of C N - , more will be the strength of ligands and more will be the value of Δ o (crystal field splitting energy).
