are resonance and isomers the same?
156101
Resonance structures are not isomers. Isomers have different arrangement of both atoms and electrons. Resonance forms differ only in arrangement of electrons. Resonance structures are a better depiction of a Lewis dot structure because they clearly show bonding in molecules.

When you draw the two mirror image isomers of a meso compound, you are just looking at different views of the same compound. A meso compound is a single compound. You can't separate it into two different compounds.

With optical isomerism, there is no difference in connectivity and no double bonds. The isomerism is to do with the arrangement of the atoms in space. It arises through the presence of a Chiral Centre. Optical isomers are Non Superimposable Mirror Images of each other; a set of optical isomers are called enantiomers.

Conformational Isomers (Conformers): Two molecules with the same configuration but different conformation. Conformational isomers are temporarily different shapes of the same molecule and for this reason are not classified as isomers in some textbooks.

Enantiomers, also known as optical isomers, are two stereoisomers that are related to each other by a reflection: they are mirror images of each other that are non-superposable. Human hands are a macroscopic analog of this. Every stereogenic center in one has the opposite configuration in the other.

1) Yes, isobars belong to the same group of elements because they have same number of protons whereas they have different number of neutrons. The atomic number of an element determines its properties.

Constitutional isomers are isomers that differ in the way that their atoms are connected. Geometric isomers are cis-trans (or E-Z) isomers; that is their atoms are all connected the same way, but their orientation in three dimensional space is different.

The movement of electrons is dictated by the electronegativity value of the atoms involved in the Lewis structure. Resonance involves the rearrangement of pi and sigma bonds within a molecule. Technically, the molecule is unchanged; the same atoms are connected together.

cyclic compounds. Geometric isomers fall under the category of stereoisomers. Stereoisomers are compounds that have the same condensed structural formula, but differ due to the arrangment of their atoms in space. ... Geometric isomers are only possible when each carbon of a double bond is bonded to two different groups.

A structural isomer, also known as a constitutional isomer, is one in which two or more organic compounds have the same molecular formulas but different structures. The two molecules below have the same chemical formula, but are different molecules because they differ in the location of the methyl group.

Isobars always have different atomic structure because of the difference in atomic numbers. The number of neutrons makes up the difference in the number of nucleons. Therefore, they are always different chemical elements having same atomic masses. Thus, isobar has different chemical properties.

Enantiomers, also known as optical isomers, are two stereoisomers that are related to each other by a reflection: they are mirror images of each other that are non-superposable.

Stability. Usually for acyclic systems trans isomers are more stable than cis isomers. This is typically due to the increased unfavorable steric interaction of the substituents in the cis isomer. Therefore, trans isomers have a less-exothermic heat of combustion, indicating higher thermochemical stability.

['they possess different physical properties.', 'they have different chemical property.', 'they show similar properties when they contain same functional group.', 'They have same molecular formula but different structural formula.', '2 isomers have different Boiling point.', 'They have same atomic weight and same number of atoms.']

Because isomers are different compounds, they have different properties. Generally, branched-chain isomers have lower boiling and melting points than straight-chain isomers. ... The more branching there is, the lower the boiling and melting points are.

In a fac isomer, any two identical ligands are adjacent or cis to each other. If these three ligands and the metal ion are in one plane, the isomer is said to be meridional, or mer. A mer isomer can be considered as a combination of a trans and a cis, since it contains both trans and cis pairs of identical ligands.

Cis isomer is an isomer where two of the same atoms are on the same side of the double bond in a molecule. A trans isomer consists of molecule with two same atoms but here the atoms lie in the opposite side of the double bond.
