Isomerism is the phenomenon in which two or more compounds have same molecular formula but their structural formula is different. The compounds are called Isomers.
There are 2 types of isomerism.
1) Structural Isomerism which is further classied into 5 more types of isomerisms:
i) Chain Isomerism which is due to difference in nature or the carbon chain e.g. isopentane, neopentane or n-pentane
ii) Position isomerism which is due to the difference in position of the functional group or unsaturated linkage in the same carbon chain. e.g. 1-Chloropropane is the isomer or 2-chloropropane or another example is 1-butene which is isomer of 2-butene
iii) Functional group isomerism in which there are different functional group but same molecular formula. e.g. dimethyl ether is functional group isomer of ethyl alcohol
iv) Metamerism is due to the unequal distribution of carbon atoms on either side of the functional group and such compounds belong to same homologous series. e.g. diethyl ether and methyl n-propyl ether are metamers.
dietheyl ether: CH3 - CH2 - O - CH2 - CH3
methyl n-propyl: CH3 - O - CH2 - CH2 - CH3
v) Tautomerism due to shifting of proton from one atom to other in the same molecule.
The 2nd type of isomerism is Cis-trans Isomerism or geometric isomerism and compounds who possess same structural formula but differ with respect to the positions of the identical groups in space are called cis-trans isomers and the phenomenon is cis-trans or geometric isomerism.
What else can I help you with?
Why an organic compound is able to show optical isomerism but not geometrical isomerism?
Optical isomerism arises due to the presence of chiral centers in a molecule, which leads to the molecule being non-superimposable on its mirror image. Geometrical isomerism, on the other hand, arises from restricted rotation around a double bond or ring. Organic compounds can exhibit optical isomerism if they have chiral centers but typically do not show geometrical isomerism unless there are specific structural features like double bonds or rings that limit rotation.
Which Type Of Isomerism Is Exhibited By But-2-Yne?
Functional group isomerism, as 1,2-butadiene and cyclobutene are its isomer, 1-butyne is its positional isomer.
Why does a tetrahedral complex of the type MA2B2 not show geometrical isomerism?
A tetrahedral complex of the type MA2B2 does not show geometrical isomerism because the ligands are the same and located in identical positions relative to the metal center, resulting in the same spatial arrangement. Geometrical isomerism arises when there is restricted rotation around a bond, leading to different spatial arrangements of ligands.
What is the shortest chain alkane that can demonstrate isomerism?
Propane (C3H8) is the shortest chain alkane that can demonstrate isomerism. It has two possible isomers: n-propane and isopropane.
What type of isomer for C2H2Br2?
Probable you think to CH2Br2, dibromomethane.
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 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 meant by position isomerism?
Position isomerism refers to a type of structural isomerism where compounds have the same molecular formula but differ in the position of a functional group or substituent on the carbon chain. This variation can lead to different chemical properties and reactivities. For example, in butanol, the hydroxyl (-OH) group can be positioned at different carbon atoms, resulting in different isomers like 1-butanol and 2-butanol.
Why an organic compound is able to show optical isomerism but not geometrical isomerism?
Optical isomerism arises due to the presence of chiral centers in a molecule, which leads to the molecule being non-superimposable on its mirror image.

Organic compounds can exhibit optical isomerism if they have chiral centers but typically do not show geometrical isomerism unless there are specific structural features like double bonds or rings that limit rotation.
Which Type Of Isomerism Is Exhibited By But-2-Yne?
Functional group isomerism, as 1,2-butadiene and cyclobutene are its isomer, 1-butyne is its positional isomer.
What has the author George W Edgett written?

Why does a tetrahedral complex of the type MA2B2 not show geometrical isomerism?
A tetrahedral complex of the type MA2B2 does not show geometrical isomerism because the ligands are the same and located in identical positions relative to the metal center, resulting in the same spatial arrangement. Geometrical isomerism arises when there is restricted rotation around a bond, leading to different spatial arrangements of ligands.
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 isomerissm?
Isomerism is the existence of molecules. This is taught in chemistry.
What does covalent bond do that an ionic bond does not?
resnance and isomerism
