QJEEM19Chb12c: JEE Main 2019 Chemistry - Class 12 JEEM19Chb12c Solution: Homoleptic octahedral complexes of a metal ion 'M 3+ ' with…

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 :

Multiple Choice Options

  • A L3 < L1 < L2
  • B L3 < L2 < L1
  • C L1 < L2 < L3
  • D L2 < L1 < L3

Step-by-Step Verified Solution

Stronger the ligand, absorption of light having lower wavelength is more.

Order of λ : Red > Green > Blue

Hence, ligand strength is L3 < L1 < L2
