From: JEE Main 2019 (Online) 9th January Evening Slot
Question
Homoleptic octahedral complexes of a metal ion 'M3+' with three monodenate ligands L1, L2 and L3 adsorb wavelenths in the region of green, blue and red respectively. The increasing order of the ligands strength is :
Choose an option
Show full solutionCorrect option: A
Correct answer
AL3 < L1 < L2
Step-by-step explanation
Stronger the ligand, absorption of light having lower wavelength is more.
Order of : Red Green Blue
Hence, ligand strength is L3 L1 L2
Order of : Red Green Blue
Hence, ligand strength is L3 L1 L2
