The structure changes in tautomers i.e. a proton leaving a carbon bond and attaching to a ketone group.
Resonance is the concept that electron density is sometimes shared between multiple bonds. In a Lewis structure, this can be expressed as double bonds swapping between two oxygens or two different set bonding set ups have Oxygen or Nitrogen bearing a formal charge.
For the actual measurement of bonds, the bond lengths between multiple resonating bonds tend to be an intermediate length between double and single bonds. This supports the idea that electron density is shared between several bonds in a resonating molecule. Benzene bonds are a good example of intermediate bond lengths due to resonance.
In Tautomerism the alpha-hydrogen is shifted where as in Resonance the PI electrons are delocalised to loss more energy and to get stability.
Isomerism refers to molecules with the same molecular formula but different structures, while tautomerism is a specific type of isomerism where molecules can interconvert by a chemical reaction, typically involving the movement of a hydrogen atom and a double bond. Tautomers exist in equilibrium with each other, with one form usually being more stable than the other.

What are stuctural isomerism?
Structural isomerism is a type of isomerism where the isomers have the same molecular formula but differ in the connectivity of atoms within the molecule. This results in different structural arrangements and different chemical and physical properties among the isomers. There are different types of structural isomerism, such as chain isomerism, positional isomerism, and functional group isomerism.
What is the significance of tautomerism in DNA bases?
Tautomerism in DNA bases can lead to incorrect base pairing during DNA replication, potentially causing mutations. This can affect the stability and fidelity of the genetic code. Understanding tautomerism is important in studying the molecular basis of genetic diseases and designing targeted therapies.
How do alkenes show geometric isomerism?
Alkenes show geometric isomerism when they have restricted rotation around the double bond, leading to different spatial arrangements of atoms. This can occur when two different groups are attached to each carbon of the double bond, resulting in cis-trans isomerism.
What is tautomerism?
Tautomerism is a type of structural isomerism where isomeric compounds exist in equilibrium through rapid interconversion involving the migration of a proton. The two tautomeric forms differ in the position of a proton and the arrangement of double bonds. Tautomerism is commonly observed in certain functional groups like carbonyl compounds and enols.
What is stereochemical structures?
Stereochemical structures refer to the three-dimensional arrangement of atoms in a molecule. They include configurations such as cis-trans isomerism, optical isomerism, and geometric isomerism, which affect the physical and chemical properties of the molecule. Knowledge of stereochemical structures is important in understanding the reactivity and behavior of organic compounds.
What is the difference between isomers and isomerism?

What is the isomerism exhibitted by propanone and 2- hydroxy propene?
Propanone (acetone) exhibits tautomerism, where it can exist in a keto form and an enol form. During tautomerism, the hydrogen and carbonyl group interchange their positions. 2-hydroxypropene exhibits geometric (E/Z) isomerism due to the presence of a carbon-carbon double bond with different substituents attached, resulting in geometric isomers.
What are the possible isomers of CH3COH?
The possible isomers of CH3COH are propanal, acetone, and methyl formate.
What is the difference between geometrical and optical isomerism?
Geometrical isomerism arises due to the restricted rotation around a bond, resulting in different spatial arrangements of atoms. Optical isomerism, on the other hand, arises due to the presence of chiral centers, leading to molecules that are non-superimposable mirror images of each other (enantiomers).
What is meant by isomerism and what are the types of isomerism?
Isomerism is when molecules have the same molecular formula but different structural arrangements or spatial orientation of atoms. The main types of isomerism are structural isomerism (different connectivity of atoms), stereoisomerism (same connectivity but different spatial arrangement), and conformational isomerism (different arrangements due to rotation around single bonds).
Why does tautomerism occur?
Because it can
Will p-benzoquinone show tautomerism?
yes:
What is the another name of geometric isomers?
Geometric isomerism also known as cis-trans isomerism or E-Z isomerism
Is cis-trans isomerism included in geometrical isomerism?
The geometrical isomerism is mainly Cis-trans isomerism but in some cases we use another term Z and E isomers, they are almost same.

What is the difference between positional isomerism and functional isomerism?
Positional isomerism refers to compounds with the same molecular formula but differing in the position of functional groups or substituents on the carbon skeleton, while functional isomerism involves compounds with the same molecular formula but differing in the functional groups present. In other words, positional isomers have the same functional groups but at different locations, whereas functional isomers have different functional groups altogether.
