What is Isomerism?

 Isomerism

Introduction

Here,we are going to know what is Isomerism,let's see and learn that what is Isomerism?

Did you think  about organic compounds which have

Same molecular formula?

Let's see break down for above statement.

Isomerism

Isomerism:

The compounds have the same molecular formula but differ from each other in physical or chemical properties,and are called isomers and phenomenon is called isomerism.

*Isomerism is due to different modes of combination of arrangement of atoms within the molecule.

There are two main types of isomerism.

1) Structural isomerism

2) Stereoisomerism

1) Structural isomerism

When the isomerism is due to difference in the arrangement of atoms within the molecule, without any reference to space,the phenomenon is called Structural isomerism.

Structural isomerism 

  "Structural isomers are compounds that have the same molecular formula but different structural formulas"

Structural isomers is of five types:

a) Chain isomerism 

b) Position isomerism 

c) Functional isomerism 

d) Metaisomarism

e) Tautomerism

2) Stereo isomerism

When isomerism is caused by the different arrangement  of atoms or groups in space,the phenomenon is called Stereoisomerism.

Stereoisomerism

"The Stereoisomers have the same structural formulas but differ in arrangement of atoms in space"

     Stereoisomerism is exhibited by such compounds which have same structural formulas but differ in configuration.

Stereoisomers is of two types:

a)Geometrical or Cis-Trans isomerism

b)optical isomerism.
