Structural Isomer's

In Organic Chemistry

Strustural isomers are molecules with the same molecular formula but different structures. There are two types of structural isomerism:

Chain isomerism

and

Functional group isomerism

Chain Isomer's

In chain isomerism molecules can be branched or in a straight chain. In other words they have a different shape, which causes them to have different physical and chemical properties.

Functional Group Isomer's

In functional group isomerism, the position of the functional group changers - and so changing the phsyical and chemical properties, and giving the isomers slightly different structures.

The diagrams below show all the isomers of C₅H₁₁OH.

As you can see their sturctures are quite different. And this particular molecule shows both chain and functional group isomerism.
