WebTautomerism is the type of isomerism where the isomers interchange into one another to be in equilibrium. This process provides more stability to the compound and it is also known by the name ‘Desmotropism’. Tautomerism takes place in presence of acid or base catalyst. In case of acid catalyst, the first step is the protonation, and the ... WebTautomerism, fast and reversible intramolecular rearrangements due to group transfer reactions (C, N, P, As, O, S, ...

WebA short answer is none really. When we refer to the enolization, we specifically refer to the process that takes you from a ketone or an aldehyde to an enol or an enolate. When we refer to a keto-enol tautomerism, we mean the equilibrium in general. Thus, by saying that my molecule undergoes the keto-enol tautomerization, I may imply the ...
Tautomers are structural isomers (constitutional isomers) of chemical compounds that readily interconvert. The chemical reaction interconverting the two is called tautomerization. This conversion commonly results from the relocation of a hydrogen atom within the compound. The phenomenon of tautomerization … See more Tautomerization is pervasive in organic chemistry. It is typically associated with polar molecules and ions containing functional groups that are at least weakly acidic. Most common tautomers exist in pairs, which means … See more Valence tautomerism is a type of tautomerism in which single and/or double bonds are rapidly formed and ruptured, without migration of atoms or groups. It is distinct from … See more The existence of multiple possible tautomers for individual chemical substances can lead to confusion.
