Isomers are compounds that have the same molecular formula but different structures. In general, a molecule will not spontaneously convert from one isomer to another.
Tautomers are a specific type of isomers. Two molecules are tautomers if they differ in the placement of a proton (H+) and a double bond, and readily convert between the two, creating an equilibrium.
For example, one common type of tautomerism is between an enol and a ketone (or aldehyde). In this case, the keto form contains a carbon double-bonded to an oxygen adjacent to a carbon with at least one hydrogen. This is in equilibrium with the enol, which is formed by moving a hydrogen from the second carbon to the oxygen (forming -OH) and the double bond to the oxygen is broken and reformed between the two carbons.

Does isomers differ in charge?
Isomers can have the same or different charge depending on their molecular structures. Isomers with different connectivity or arrangement of atoms might have different charges due to variations in the distribution of electrons. However, isomers with the same molecular formula but different structural arrangements will have the same overall charge.
Is it true that atoms with the same number of protons but diffrent numbers of neutrons are called isomers?
Not isomers, Isotopes
Does RNA have isomers?
Yes, RNA can have isomers. Isomers are molecules with the same molecular formula but different structural arrangements. In the case of RNA, isomers can arise due to differences in the sequence or arrangement of nucleotides within the RNA molecule.
Do isomers have the same molecular formula?
Yes, isomers are compounds that have the same molecular formula but different structural arrangements or spatial orientations of their atoms.
What is tautomerism?
Tautomerism refers to an equilibrium between two different structure of the same compound. Usually the tautomers differ in the point of attachment of a hydrogen atom.Tautomers are two forms of a compound that interconvert by a process known as tautomerization. A common type of tautomer is found with ketones. This is called keto-enol tautomerism. The ketone and its enol form are readily interconvertible constitutional isomers that exist in equilibrium with each other. Isomers that differ from each other only in the location of a hydrogen atom and a double bond are proton isomers. Proton tautomers are isomers in which a hydrogen atom and a double bond switch locations between a carbon atom and a heteroatom (which is an atom other than carbon, such as oxygen or nitrogen). There is a rule which states, called Erlenmeyer Rule, which states that all alcohols in which the hydroxyl group is attached directly to a double-bonded carbon atom become aldehydes or ketones. This occurs because the keto form is generally more stable than its enol tautomer. Tautomers differ from each other in locations of atoms as well as electrons, and so are NOT resonance contributors, which are different representations of the same structure.See the Web Links to the left for some diagrams of molecules with are tautomers for a better understanding and more information.
What is the relationship between keto and enol tautomers?
Keto and enol tautomers are constitutional isomers that interconvert by the movement of a proton. Keto tautomers have a carbonyl group, while enol tautomers have a hydroxyl group connected to a carbon-carbon double bond. These two forms are in equilibrium with each other in certain compounds.
How vinyl chloride and acetyldehyde are keto enol tautomers?
In the keto form, vinyl chloride has a carbonyl (C=O) group, while in the enol form, it has an alcohol (-OH) group. Acetaldehyde in its keto form has a carbonyl group, and in its enol form, it has a double bond between a carbon and an oxygen atom. Tautomers are isomers that can interconvert by a proton transfer.
Do isomers have the same boiling point?
Isomers are molecules with the same chemical formula but different structures. Due to their different structures, isomers can have different boiling points.
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 two tautomeric forms of cytosine?
The amino and inimo forms are the two tautomers of cytosine. The differ due to resonsnce around the double bond between C1 and N in the ring and C1 and N in the side chain. The amino and inimo forms are the two tautomers of cytosine. The differ due to resonsnce around the double bond between C1 and N in the ring and C1 and N in the side chain.
What is Tautomer?
Tautomers are isomers of a compound that can readily interconvert, usually differing in the position of a proton and the double bond. This process, known as tautomerization, often involves the movement of a hydrogen atom and a shift in the bonding of electrons. A common example is the keto-enol tautomerism, where a ketone and an enol form exist in equilibrium. Tautomers typically have distinct chemical properties and reactivities, influencing their roles in biological and chemical processes.
What is the difference between configurational and constitutional isomers?
Configurational isomers have the same atoms connected in the same order but differ in spatial arrangement, while constitutional isomers have the same molecular formula but differ in the connectivity of atoms.
What is the term for compounds that have the same molecular formula but a different molecular shape?
Isomers.
What two sugar isomers have in common?
If they're isomers, they by definition have the same molecular formula.
What are molecules with the same molecular formulas but different structural formulas called?
Molecules with the same molcular formulae but differing structural formulae are called isomers.
Does isomers differ in charge?
Isomers can have the same or different charge depending on their molecular structures. Isomers with different connectivity or arrangement of atoms might have different charges due to variations in the distribution of electrons. However, isomers with the same molecular formula but different structural arrangements will have the same overall charge.
What are compuonds withe the same cheimcial formule but different structure?
Isomers are compounds with the same chemical formula but different structures. They can have different physical and chemical properties due to their unique arrangement of atoms. Examples include structural isomers, geometric isomers, and optical isomers.
