What is isomerism? Which are the types of isomerism?
The phenomenon of existence of two or more compounds possessing the same molecular formula but different properties is known as isomerism. Such compounds are called as isomers.
The types of isomerism are as follows:
$1$. Structural isomerism:
- Chain isomerism
- Position isomerism
- Functional group isomerism
- Metamerism
$2$. Stereoisomerism:
- Geometrical isomerism
- Optical isomerism
