ISOMERISM Meaning and
Definition
-
Isomerism is a term used in chemistry to describe the phenomenon whereby compounds with the same molecular formula have different structural arrangements or connectivity of atoms. It refers to a situation in which molecules exhibit varying arrangements of atoms, leading to differences in their physical and chemical properties. Isomerism arises when the atoms within a molecule can be rearranged to form different structures while maintaining the same number and type of atoms.
There are different types of isomerism, including structural isomerism, stereoisomerism, and geometric isomerism. Structural isomers have different arrangements of atoms bonded in the molecule, resulting in diverse chemical properties. Stereoisomerism occurs when the connectivity of atoms is identical, but the spatial arrangement in 3D space differs. Geometric isomerism specifically relates to the different arrangement of atoms around a double bond or within a cyclic structure.
Isomerism plays a crucial role in organic chemistry as it affects the reactivity, stability, and biological activity of compounds. The ability to identify and differentiate isomers is crucial for understanding their properties and behavior. Isomerism has broad applications in pharmaceuticals, agrochemicals, materials science, and other fields, as slight variations in molecular structure can drastically influence the properties and functions of compounds. Research and study of isomerism have helped advance knowledge in drug design, chemical synthesis, and understanding molecular behaviors in various chemical processes.
In conclusion, isomerism refers to the occurrence of compounds with identical molecular formulas but differing in the arrangement or connectivity of their atoms. It is a fundamental concept in chemistry that encompasses different types of isomers, which can have significant implications on the behavior and properties of chemical compounds.

Common Misspellings for ISOMERISM
Etymology of ISOMERISM
The word "isomerism" is formed by combining the prefix "iso-" and the suffix "-merism".
The prefix "iso-" comes from Greek, meaning "equal" or "same". It is often used in chemistry to indicate a substance or compound that has the same molecular formula but different structural arrangements.
The suffix "-merism" is derived from the Greek word "meros", meaning "part" or "segment". In this context, it refers to the arrangement or structure of the isomers.
Therefore, the term "isomerism" essentially means the phenomenon of having the same molecular formula but different structural arrangements or parts.
