Question

The absorption maxima for three octahedral complexes [ M ( L ₁)₆]³⁺ , [ M ( L ₂)₆]³⁺ and [ M ( L ₃)₆]³⁺ are observed at 450 nm , 650 nm and 550 nm respectively. The correct increasing order of the ligand field strength of L ₁ , L ₂ and L ₃ is:

Quantrex Academy · Accepted Answer

Correct answer: C. L ₂ < L ₃ < L ₁

The crystal field splitting energy ( _o ) is equal to the energy of the light absorbed by the coordination complex. The energy of the absorbed light is inversely proportional to its wavelength ( ), given by the relation E = hc . A stronger field ligand causes a larger crystal field splitting ( _o ), which means the complex will absorb light of higher energy and shorter wavelength. The given absorption wavelengths are: L ₁ = 450 nm L ₂ = 650 nm L ₃ = 550 nm The order of wavelengths is L ₁ Therefore, the increasing o
