WebIsomers. Isomers are compounds with the same molecular formulae but different structural formulae. They have the same number of each type of atom. They can be part of the same or different homologous series, e.g. alkenes and cycloalkanes can be isomers. Due to their different structures their physical properties (melting point, boiling point ...
