Chain isomers

  • Chain isomers are molecules that have the same molecular formula but one is linear and one is branched. For example:
    • Butane is a linear molecule with the molecular formula C4H10.
    • Methylpropane is a branched molecule with the molecular formula C4H10.

Position isomers

  • Position isomers are molecules that have the same molecular formula but have their functional group in different places. For example:
    • Butan-1-ol has a hydroxyl group attached to carbon-1.
    • Butan-2-ol has a hydroxyl group attached to carbon-2.

Functional group isomers

  • Functional group isomers are isomers that have had their structures changed so that they have different functional groups. For example:
    • Propanoic acid.
    • Methyl ethanoate.
