Tautomer - Wikipedia
The two tautomers of an amino acid: (1) neutral and (2) zwitterionic forms. In chemistry, tautomers (/ ˈtɔːtəmər /) [1] are structural isomers (constitutional isomers) of chemical compounds that readily interconvert. [2][3][4][5] The chemical reaction interconverting the two is called tautomerization. This conversion commonly results from ...
9.4.2. Tautomers - Chemistry LibreTexts
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.
Tautomers - Chemistry LibreTexts
2022年2月28日 · Tautomers are constitutional isomers that differ from each other in the locations of a hydrogen atom and one or more double bonds and interconvert rapidly.
Tautomerism - Meaning, Definition, Types, Examples, Reactions
The two structures are called tautomers, and these types of isomer compounds usually differ only in the number of electrons and protons. They also exist in dynamic equilibrium.
23.2: Enols, Enolate Ions and Tautomerization
Because of the acidity of the alpha-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.
Stereochemistry, Isomerism & Equilibria - Britannica
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 …
Keto-Enol Tautomerism : Key Points - Master Organic Chemistry
2022年6月21日 · Aldehydes and ketones that have a proton on the alpha carbon can participate in keto-enol tautomerism, where an equilibrium exists between two constitutional isomers – the keto and enol forms. Constitutional isomers that are in equilibrium are called “tautomers”.
