Isomers are molecules that have the same molecular formula but different arrangements of atoms. This means they have the same types and numbers of atoms but differ in their structural arrangements.
There are different types of isomers, including:
* Structural isomers: Differ in the connectivity of their atoms.
* Stereoisomers: Have the same connectivity but differ in the spatial arrangement of their atoms. This includes:
* Enantiomers: Non-superimposable mirror images of each other.
* Diastereomers: Stereoisomers that are not mirror images of each other.
For example, glucose and fructose both have the molecular formula C6H12O6, but they are isomers because they have different arrangements of atoms.
