2.4.1 Isomerism

Isomerism

  1. Isomers are compounds with the same molecular formula but different structural formulae.
  2. Isomerism is the existence of two or more compounds that have the same molecular formula but different structural formulae.
    Examples of the two isomers of butane
    (The 2 molecules have same molecular formulae but different structural formulae)
  3. Isomers have different physical properties because they have different molecular structures.
  4. However, isomers have the same chemical properties because they belong to the same homologous series.
