JEE Main 2014 — Coordination Compounds Question with Solution
From: JEE Main 2014 (Offline)
Question
The octahedral complex of a metal ion M3+ with four monodentate ligands L1, L2, L3 and L4 absorb wavelengths in the region of red, green, yellow and blue, respectively. The increasing order of ligand strength of the four ligands is :

Correct answer
DL1 < L3 < L2 < L4
Step-by-step explanation
For a given metal ion, weak filed ligands create a complex with smaller , which will absorbs light of longer and thus lower frequency. Conservely, stronger filled ligands create a larger absorb light of shorter and thus higher higher energy.
So order of ligand strength is
