Isomer - Wikipedia
网页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.

网页2024年9月5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.

网页2017年6月12日 · Isomers are two molecules with the same molecular formula but differ structurally. Therefore, isomers contain the same number of atoms for each element, but the atomic arrangement differs.
What are Isomers? - ChemTalk
网页What is an Isomer? Isomers are similar molecules with different structural characteristics. Although having the same number of atoms in each element, isomers have different atomic arrangements. Even with the same molecular formula, molecules often have different physical characteristics, especially if their respective functional groups are unique.

网页Isomers are molecules that have the same molecular formula, but have a different arrangement of the atoms in space. Consider butane: There are also endless other possible ways that this molecule could twist itself. There is almost completely free rotation around all the carbon-carbon single bonds.
Definition, Detailed Explanation, Types, Examples of Isomerism
网页Isomerism in organic chemistry is a phenomenon shown by two or more organic compounds having the same molecular formula but different properties due to difference in arrangement of atoms along the carbon skeleton (structural isomerism) or in …
3.4: Isomers - Chemistry LibreTexts
网页We have defined isomers in a very general way as nonidentical molecules that possess the same number and kind of atoms. However, there are several ways in which isomers can be nonidentical. Among the alkenes, 1- and 2-butene are position isomers, because in these compounds the double bond has a different position in the carbon chain
