Chemistry - Coordination Chemistry Question with Solution | TestHub
Structural isomerism arises due to the difference in the type of chemical linkages and distribution of ligands within and outside the coordination sphere whereas stereoisomers differ only with respect to the spatial orientation of ligands in space around the metal ion.
Select the type of complex which have the ratio of total number of enentiomeric pairs to the total number of stereoisomers equal to .
Options:
Answer:
Solution:
A ratio of for indicates that all possible stereoisomers of the complex are optically active (chiral), meaning there are no optically inactive (achiral/meso) forms.
In the complex , where is an unsymmetrical bidentate ligand and is a monodentate ligand, the spatial restrictions of the chelate rings prevent any plane or center of symmetry in its configurations.
Consequently, all of its geometrical configurations are non-superimposable on their mirror images, making every single stereoisomer part of an enantiomeric pair. This ensures that the number of enantiomeric pairs is exactly half the total number of stereoisomers, satisfying the given ratio of .
