Isomer and Naming According to IUPAC (2)

2-methylprop-1-ene

Isomer (1)

Isomers are molecules that have the same molecular formula but different structural formulae

Way structural isomerism occur

Structural isomerism can occur in several ways such as chain isomerism and position isomerism

Function of functional group isomerism

Functional group isomerism is also a type of structural isomerism

Example of structural isomer - Chain Isomerism

Example of structural isomer - Position Isomerism

Isomer (2)

The isomers show the same chemical properties because each isomer has the same functional group

Isomer (3)

The isomers show the physical properties, such as melting point and boiling point, are different

Isomer (4)

The more branches of isomers there are, the lower the melting point and boiling point are

Isomer (5)

Generally, the number of isomers of a molecule increases with the increase of the number of carbon atoms in the molecule
