Isomer - Wikipedia
In chemistry, isomers are molecules or polyatomic ions with identical molecular formula – that is, the same number of atoms of each element – but distinct arrangements of atoms in space. [1] Isomerism refers to the existence or possibility of isomers.
5.1: Isomers - Chemistry LibreTexts
Isomers are molecules with the same molecular formulas, but different arrangements of atoms. There are several different types of isomers which will be described and a flowchart (see figure below) can help you determine which type of isomers are present.

2024年10月17日 · Isomerism, the existence of molecules that have the same numbers of the same kinds of atoms (and hence the same formula) but differ in chemical and physical properties. Isomers are chemical compounds that have the same parts but are not the same. Learn more about isomerism in this article.

2022年11月17日 · Because no bonds are broken in going from (a) to (d) or from (b) to (c), these alternative representations are not structural isomers. The three structural isomers—either (a) or (d), either (b) or (c), and (e)—have distinct physical and chemical properties.
Isomer: Definition, Types, Structures, and Examples - Chemistry …
Isomers are structures with the same molecular formula and chemical composition but different arrangements of atoms in space [1-4]. There are two main types of isomers: structural isomers and stereoisomers [1-8]. Structural isomers are also called constitutional isomers.
Definition, Detailed Explanation, Types, Examples of Isomerism
Isomerism is the phenomenon in which more than one compounds have the same chemical formula but different chemical structures. Chemical compounds that have identical chemical formulae but differ in properties and the arrangement of atoms in the molecule are called isomers. Therefore, the compounds that exhibit isomerism are known as isomers.

2018年12月3日 · When atoms can assume different configurations, the phenomenon is termed isomerism. There are several categories of isomers, including structural isomers, geometric isomers, optical isomers, and stereoisomers. Isomerization can occur spontaneously or not, depending on whether the bond energy of the configurations is comparable.

Isomers are molecules with the same molecular formulas, but different arrangements of atoms. A structural isomer is one in which two or more organic compounds have the same molecular formulas, but different structures.
