  • Isomers are compounds with the same molecular formula.

    eg. 1:  Butane and isobutane have the same molecular formula: C4H10. Therefore, they are isomers.

     

     

    eg. 2:  Maleic acid and fumaric acid have the same molecular formula: C4H4O4.  Therefore, they are isomers.

     

     

    eg. 3:  (R)-Lactic acid and (S)-Lactic acid have the same molecular formula: C3H6O3.  Therefore, they are isomers.
