Optical isomerism is shown by octahedral complexes

A

having all monodentate ligands

B

having all the three bidentate ligands

C

having two trans bidentate ligands

D

having two trans monodentate ligands

Text Solution

Verified by Experts

The correct Answer is:
B
Octahedral complexes containing three bidentate ligands shows optical isomerism .If A is a bidentate ligand then complex of type `M (AA) _(3 )` shows optical isomerism

Geometrical isomerism arises in heteroleptic complexes due to different possible geometrical arrangement of the ligands. Important examples of this behaviour are found with coordination number 4 and 6. Such isomerism is not possible for a tetrahedral geometry but it is possible for square planar as well as octahedral complexes. Optical square planar as well as octahedral complexes. Optical square planar as well as octahedral complexes. Optical isomers are mirror images that cannot be superimposed on one another. These are called enantiomers. Optical isomerism is common in octahedral complexes involving bedentate ligands. Which of the following complexes will show geometrical isomerism ?
