Isomer and Isomerism
An isomer is a molecule that has a identical molecular formula means the number of atoms of each type should be the same but differs in the arrangement of atoms in space.
While,
Isomerism is the phenomenon in which more than one compounds have the same chemical formula but have a difference in their chemical structures.
Example: n-Butane and isobutane are isomers of Butane. They have same molecular formula C4H10 while if see the arrangement, then in n-butane, there is a straight chain of 4 carbon atoms while in isobutane there is a straight chain of three carbon and the fourth carbon is linked to the middle carbon as a branch.
Structural Isomerism
Structural Isomerism is the phenomenon of organic compound having same molecular formula but different structural arrangements. The compounds which shows the property of structural isomerism are called Structural Isomers. There are in total six types of structural isomerism.
In this article, we will learn in detail about structural isomers, structural isomerism, its types and examples in detail. Before getting into Structural Isomerism, let’s understand first What is an Isomer?
