Ma3b3 complex does not show Optical Isomerism....
It shows Geometrical Isomerism instead....
Its easy to find them...
The complex compound should have atleast One CENTRAL METAL ION which is bonded to all different Ligands ie. Asymmetric ....simple...:)
And, Optical Isomerism is not possible in Ma3b3, because u have same amount of "a" ligand and "b" ligand... so Rotation is not possible....
P.S- pls do Rate if u find it True and Honest...:) ty.
