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."Stated colloquially, isomers are chemical compounds that have the same parts but are nonetheless not the same.
Isomers are molecules or ions with the same formula but different arrangements of atoms. Learn about structural, stereo, tautomer and resonance isomers, and see how they differ in shape and properties.
Geometric (cis/trans) isomers. 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.
Learn what isomerism is and how it occurs in different types of compounds. Explore the examples of chain, positional, functional, metameric, tautomeric, ring chain and stereoisomerism.
Isomerism is the phenomenon of having different compounds with the same chemical formula but different structures and properties. Learn about the types of isomerism, such as structural, stereo, ionization and tautomerism, with examples and diagrams.
Learn about isomers, molecules with the same formula and composition but different arrangements of atoms in space. Explore the types of isomers, such as structural, stereoisomers, and conformational, with diagrams and examples.
The term isomerism comes from the Greek words isos, meaning "equal," and meros, meaning "parts." We can define isomerism as: Two or more compounds having the same molecular formula but differing in the physical and chemical properties are called isomers, and the phenomenon is known as isomerism.
Isomerism is the phenomenon where molecules with the same formula have different structures and properties due to their arrangement of atoms. Learn about the types of isomerism, such as chain, position, functional group, and stereoisomerism, and see real-world examples and applications.
Isomerism: Isomerism is a phenomenon where two or more compounds have the same molecular formula but differ in their structural or spatial arrangement, leading to distinct chemical and physical properties. Isomerism can arise due to differences in connectivity (structural isomerism), spatial orientation (stereoisomerism), or both.
Isomerism is broadly categorized into two types: structural isomerism and stereoisomerism. Structural isomerism occurs when molecules have the same molecular formula but different bonding patterns. Stereoisomerism happens when molecules have the same sequence of bonded atoms but differ in three-dimensional orientations.
