Question

How to find optical isomers in coordination compounds?

Answer 1

ISOMERISM!

Complex which have the same molecular formula, i.e. same chemical composition but different in the structure arrangement of atoms are called Isomerism. These isomers have different properties. The phenomenon that give rise to the different isomers is called isomerism.

Coordination compound exhibit two type of isomerism

1.  Structural isomerism

2. Stereoisomerism

Stereoisomerism

• Geometrical Isomerism
• optical Isomerism

Optical Isomerism

coordination compound having same molecular formula but different in their ability to rotate directions of the plane polarised light are said to exhibit optical isomerism.

Optical Isomerism can be find by the following ways...

1.  plane of symmetry

2. centre of symmetry

3. Alternating axis of symmetry

General formula of Optically active Compound!

1. [M(AA)3] , [M(AA)2a2], [M(AA)2ab][M(AA)a2b2]

2. [Ma2b2c2] , [Mabcdef] , [M(AB)3].

By Checking the Cis And Trans Isomerism one can also predict the optical Isomerism.

Answer 2

$Answer$

There are two ways optical isomers can be determined: using mirror images or using planes of symmetry. Optical isomers do not exhibit symmetry and do not have identical mirror images. Let's go through a quick review of symmetry and mirror images.
