JEE Main 2014Coordination Compounds Question with Solution

JEE Main 2014 (06 Apr)

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
BL1 < L3 < L2 < L4

Step-by-step explanation

The colors of wavelengths are absorbed in decreasing order of wavelengths.

λ red > λ yellow > λ green > λ blue

as ΔE=hcλ

Δ E Red < Δ E Yellow < Δ E Green < Δ E Blue

L1 < L3 < L2 < L4

As the order of ligand field strength provides the order of relative crystal field splitting energies.
