Tautomer - Wikipedia
网页The phenomenon of tautomerization is called tautomerism, also called desmotropism. Tautomerism is for example relevant to the behavior of amino acids and nucleic acids, two of the fundamental building blocks of life.
Tautomerism - Meaning, Definition, Types, Examples, Reactions
网页Tautomerism is a phenomenon where a single chemical compound tends to exist in two or more interconvertible structures that are different in terms of the relative position of one atomic nucleus, which is generally hydrogen.
Tautomerism | Stereochemistry, Isomerism & Equilibria
网页Tautomerism, the existence of two or more chemical compounds that are capable of facile interconversion, in many cases merely exchanging a hydrogen atom between two other atoms, to either of which it forms a covalent bond. Unlike other classes of isomers, tautomeric compounds exist in mobile.
9.4.2. Tautomers - Chemistry LibreTexts
网页Here is one more. Tautomers are two molecules with the same molecular formula but different connectivity - constitutional isomers, in other words - which can interconvert in a rapid equilibrium. The most common tautomeric relationship in organic chemistry is the keto-enol pair. 13.1A: Keto-enol tautomerization.
22.1: Keto-Enol Tautomerism - Chemistry LibreTexts
网页Because of the acidity of α-hydrogens, many carbonyl containing compounds undergo a proton-transfer equilibrium called tautomerism. Tautomers are readily interconverted constitutional isomers, usually distinguished by a different location for an atom or a group.
22.1 Keto–Enol Tautomerism - Organic Chemistry - OpenStax
网页This spontaneous interconversion between two isomers, usually with the change in position of a hydrogen, is called tautomerism, from the Greek tauto, meaning “the same,” and meros, meaning “part.” The individual keto and enol isomers are called tautomers.
Tautomerism: Definition, Types, Examples, Mechanism and …
网页2023年5月15日 · Tautomers are isomers of a compound that differ only in the position of the protons and electrons. The carbon skeleton of the compound is unchanged. A reaction that involves simple proton transfer in an intramolecular fashion is called tautomerism. The molecules showing tautomerism exist under dynamic equilibrium.
Tautomerism | Overview & Research Examples - Perlego
网页Tautomerism is a chemical phenomenon where a molecule can exist in two or more forms that differ in the position of a proton or a double bond. These forms are called tautomers and can interconvert rapidly. Tautomerism is important in biochemistry and organic chemistry.
23.2: Enols, Enolate Ions and Tautomerization
网页Because of the acidity of α hydrogens, carbonyls undergo keto-enol tautomerism. Tautomers are rapidly interconverted constitutional isomers, usually distinguished by a different bonding location for a labile hydrogen atom and a differently located double bond.
