Isomer - Wikipedia Two main forms of isomerism are structural (or constitutional) isomerism, in which bonds between the atoms differ; and stereoisomerism (or spatial isomerism), in which the bonds are the same but the relative positions of the atoms differ Isomeric relationships form a hierarchy
8. 1: Types of Isomers - Chemistry LibreTexts Objective After completing this section, you should be able to explain the differences among constitutional (structural) isomers and stereoisomers (geometric isomers)
Isomerism | Definition, Types, Examples | Britannica 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 ”
Isomer Definition and Examples in Chemistry - ThoughtCo Isomers are molecules with the same atoms but arranged in different ways, giving them unique properties Structural isomers differ in how atoms are joined, while stereoisomers differ in atom placement in space Isomers are important in medicine since enzymes often work with only one kind of isomer
What Is an Isomer? Definition and Types - ScienceInsights Isomers are molecules that share the same chemical formula but have a distinct arrangement of atoms in space This subtle difference in atomic organization can lead to vastly different physical and chemical properties, as it dictates a molecule’s shape and how it interacts with other molecules
