Homologous series are groups, or families, of organic compounds that contain the same functional groupings and whose members differ by only one -CH2- group of atoms. The physical properties within an homologous series show a general trend due to this difference.
A homologous series is a series of compounds of the same family, with the same general formula, which differ from each other by a common structural unit.
