write a note on functional isomerism
Answers
Answer:
Isomerism is the phenomenon in which more than one compounds have the same chemical formula but different chemical structures. Chemical compounds that have identical chemical formulae but differ in properties and the arrangement of atoms in the molecule are called isomers. Therefore, the compounds that exhibit isomerism are known as isomers.
The word “isomer” is derived from the Greek words “isos” and “meros”, which mean “equal parts”. This term was coined by the Swedish chemist Jacob Berzelius in the year 1830.
Types
There are two primary types of isomerism, which can be further categorized into different subtypes. These primary types are Structural Isomerism and Stereoisomerism. The classification of different types of isomers is illustrated below.
Isomerism
Structural Isomerism
Structural isomerism is commonly referred to as constitutional isomerism. The functional groups and the atoms in the molecules of these isomers are linked in different ways. Different structural isomers are assigned different IUPAC names since they may or may not contain the same functional group. The different types of structural isomerism are discussed in this subsection.
Chain Isomerism
It is also known as skeletal isomerism.
The components of these isomers display differently branched structures.
Commonly, chain isomers differ in the branching of carbon
An example of chain isomerism can be observed in the compound C5H12, as illustrated below.
Chain Isomerism
Answer:
Functional isomerism occurs when substances have the same molecular formula but different functional groups. This means that functional isomers belong to different homologous series
