Question
Chemistry Question on Werner’s Theory of Coordination Compounds
The octahedral complex of a metal ion M3+ with four monodentate ligands L1,L2,L3andL4 absorb wavelengths in the region of red, green, yellow and blue, respectively. The increasing order of ligand strength of the four ligands is
A
L4<L3,L2<L1
B
L1<L3<L2<L4
C
L3<L2<L4<L1
D
L1<L2<L4<L3
Answer
L1<L3<L2<L4
Explanation
Solution
The energy of red light is less than that of violet light
So energy order is
Red $
