Two types of isomerism are ___ and ___.
The phenomenon of isomerism occurs when two or more compounds have the same chemical formula but distinct chemical structures.
There are two main forms of isomerism, each of which can be further divided into subgroups. Structural isomerism and Spatial isomerism are the two main forms.
Constitutional isomerism is a term used to describe structural isomerism. The functional groups and atoms in these isomers' molecules are connected in various ways.
Spatial isomerism occurs when molecules with the same chemical formula have various orientations of their atoms in three-dimensional space.
Hence, two types of isomerism are structural isomerism and spatial isomerism.
