Isomer: Definition, Types, Structures, and Examples - Chemistry …
An example of a pair of functional isomers is propanal and propanone (acetone). Both have the molecular formula C 3 H 6 O. Propanal is an aldehyde, while propanone is a ketone. Another example pair is glucose and fructose. Stereoisomers have the same connectivity of atoms but are arranged differently in space.
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. Isomers do not necessarily share similar chemical or physical properties.

2017年6月12日 · Example of an Isomer. There are several examples of isomers, described as follows: Methoxyethane and Propanol. The chemical structure, C 3 H 8 O exists as several isomers of propanol, as well as the isomer methoxyethane.
Types of Isomers: Constitutional, Stereoisomers, Enantiomers, and ...
2018年9月10日 · Here we explain the different types of isomers - constitutional, stereoisomers, enantiomers and diastereomers - and see how it's like family relationships.
8.1: Types of Isomers - Chemistry LibreTexts
2022年11月17日 · With a molecule such as 2-butene, a different type of isomerism called geometric isomerism can be observed. Geometric isomers are isomers in which the order of atom bonding is the same but the arrangement of atoms in space is different. The double bond in an alkene is not free to rotate because of the nature of the bond.
Isomerism | Definition, Types, & Examples | Britannica
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. The roots of the word isomer are Greek— isos plus meros, or “equal parts.”
Constitutional isomers - 3.4: Isomers - Chemistry LibreTexts
Example: Isomers in C 3 H 6 O A molecular formula $$C_3H_6O$$ could be either propanal ( an aldehyde ) or propanone ( a ketone ). There are other possibilities as well for this same molecular formula – for example, you could have a carbon-carbon double bond (an alkene) and an -OH group (an alcohol) in the same molecule.
What are Isomers? - ChemTalk
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.
Isomerism: Definition, Types, Examples - Science Info
2023年6月9日 · Isomers are molecules having the same molecular formula but various atom configurations, and the phenomenon is therefore called Isomerism. Isomers differ in their physical and chemical properties. Isomerism occurs when many substances have the same chemical formula but different chemical structures.
