What Are Isomers?

Chemically , isomerism refers to compounds that have the same chemical formula , have the same chemical bond, but have different atomic arrangements. Simply put, the phenomenon that compounds have the same molecular formula but different structures is called isomerism ; compounds with the same molecular formula but different structures are isomers of each other. Such as: ethanol and methyl ether.

Definition: Chemically, an isomer is one that has the same molecular formula but differs.

Stereoisomerism

Enantiomers are molecules that are mirror images of each other and cannot overlap. They are in

Diastereomers refer to all stereoisomers that are not enantiomers, that is, optical isomers that are not in a mirror image relationship. It includes meso compounds, cis-trans isomers, conformers and stereoisomers with one or more chiral centers but not in a mirror image relationship. In general, they not only have different optical properties, but also many physical and chemical properties. ^[1]
