Structural Isomerism: Chain, Position, and Functional
Chain Isomerism:
Chain isomerism involves the arrangement of atoms within a molecule that is not present in other isomers. This can occur due to differences in the lengths and types of carbon chains. For example, the molecules butane, isobutane, and pentane all have the same molecular formula (C4H10), but their structures are different due to the arrangement of the carbon atoms.
Positional Isomerism:
Positional isomerism involves the arrangement of atoms around a central atom. This can occur due to differences in the location of substituents or functional groups. For instance, the molecules cis-2-butene and trans-2-butene have the same molecular formula (C4H8), but their structures are different because of the arrangement of the carbon atoms around the central carbon atom.
Functional Isomerism:
Functional isomerism involves the presence of the same functional group in different molecules. This can occur when a functional group can be attached to different carbon atoms. For example, the molecule phenol has the functional group -OH attached to the aromatic ring, while the molecule acetone has the functional group -COCH3 attached to the carbon atom
