The octahedral complex of a metal ion `M^(3+)` with four monodentate ligands `L_(1),L_(2),L_(3)` and `L_(4)` absorb wavelengths in the region of red,green, yellow and bule, respectively The increasing order of ligand strengh of the four ligands is

A

`L_(3)ltL_(2)ltL_(4)ltL_(1)`

B

`L_(1)ltL_(2)ltL_(4)ltL_(3)`

C

`L_(4)ltL_(3)ltL_(2)ltL_(1)`

D

`L_(1)ltL_(3)ltL_(2)ltL_(4)`

Text Solution

Verified by Experts

The correct Answer is:
