JEE Mains · Chemistry · STD 12 - 5. Co-ordination chemistry
Homoleptic octahedral complexes of a metal ion \('{M^{3 + }}'\) with three monodentate ligands \(L_1, L_2\) and \(L_3\) absorb wavelengths in the region of green, blue and red respectively. The increasing order of the ligand strength is
- A \(L_3 < L_1 < L_2\)
- B \(L_3 < L_2 < L_1\)
- C \(L_1 < L_2 < L_3\)
- D \(L_2 < L_1 < L_3\)
Answer & Solution
Correct Answer
(A) \(L_3 < L_1 < L_2\)
Step-by-step Solution
Detailed explanation
\(\begin{array}{*{20}{c}} {{L_1}}&{{L_2}}&{{L_3}} \\ {Green}&{Blue}&{\operatorname{Re} d} \end{array}\) absorbed wave length order of \(\lambda \) \(Red > Green > Blue\) \(L_3 > L_1 > L_2\) \(\therefore \) Strength of ligand \(\alpha \,\,\Delta \,\,\alpha \,\,1/\lambda\)…
