ISOMERISM
Stereo Isomerism
Optical isomer
An optical isomerism is the phenomenon in which the two isomeric forms can rotate the plane of polarized light in opposite direction. These are called optical isomers display identical characteristics in terms of molecular weight as well as chemical and physical properties.

Geometrical isomer
Cis
In the cis isomer, the two functional groups are arranged on the same side of a double bond.
-
Trans
In the trans isomer, the two functional groups are arranged on the opposite side of a double bond.
-
Geometric isomers are two or more coordination compounds which contain the same number and types of atoms, and bonds (i.e., the connectivity between atoms is the same), but which have different spatial arrangements of the atoms. Not all coordination compounds have geometric isomers.
When isomerism is caused by the different arrangements/ orientation of atoms or groups in space, the phenomena is called stereo isomerism
Structural Isomerism
Tautomersim
A tautomer of a compound refers to the isomer of the compound which only differs in the position of protons and electrons. Typically, the tautomers of a compound exist together in equilibrium and easily interchange. It occurs via an intramolecular proton transfer.
-
Position Isomerism
In position isomerism, the basic carbon skeleton remains unchanged, but important groups are move d around on that skeleton.
-
-
-
Metamerism
This type of isomerism is due to unequal distribution of carbon atoms on either side of the functional group. Such compounds are member of Homologous series
-
Structural isomerism is due to difference in the arrangement of atoms within the molecule, without any reference to space.
Isomerism is the phenomenon in which more than one compounds have the same chemical formula but different chemical structures
