What is tautomerism in chemistry class 11?

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 the hydrogen.

What is tautomerism Ncert?

-The phenomenon in which a single chemical compound tends to exist in two or more interconvertible structures that differ in terms of the position of one atomic nucleus which is generally a hydrogen is known as tautomerism.

What is keto enol tautomerism Class 11?

The “keto-enol” tautomerism is an acid/base catalysed mechanism where the carbonyl form is initially protonated and thereby the conjugate base formed extracts proton from one of the alkyl carbon atoms while the shared electron share between the hydrogen atom and the carbon atom forms the double bond forming the enol.

What is tautomerism example?

Ketone-enol, enamine-imine,lactam-lactim are some of the examples of tautomers. Meanwhile, some key features of Tautomerism are that this process provides more stability for the compound. In this phenomenon, there exists an exchange of a hydrogen atom between two other atoms while forming a covalent bond to either one.

What is tautomerism Slideshare?

When two structural isomers are mutually interconvertible & exist in dynamic equilibrium they are called tautomers & the phenomenon is called tautomerism. Uracil.  Aldehydes, ketones & other carbonyl compounds ( e.g. esters) exhibit this special type of tautomerism.

What is an example of tautomerism?

Tautomerism Example Ketone-enol, enamine-imine,lactam-lactim are some of the examples of tautomers. Meanwhile, some key features of Tautomerism are that this process provides more stability for the compound.

How many forms of tautomerism are there?

two tautomers
The two tautomers of an amino acid: (1) neutral and (2) zwitterionic forms.

What groups show tautomerism?

Tautomerism is an isomerism in which the isomers are readily interchangeable and are in dynamic equilibrium with each other. It is shown by the compounds which have an acidic α−hydrogen. Keto compounds show tautomerism. Recall the keto-enol tautomerism.

What is tautomerism give example?

Tautomers are constitutional isomers of two compounds that readily interconvert between one another. One of the most common examples of tautomers are the isomers of phenol. In tautomerization, the atoms in a molecule will rearrange themselves to form a different structure.
