Give a simple and informative explanation
A series of organic compounds in which every succeeding member differs from the previous one by –CH2 or 14 u. The molecular formula of all the members of a homologous series can be derived from a general formula.
CH4 and C2H6 — these differ by a –CH2- unit
C2H6 and C3H8 — these differ by a –CH2- unit
Therefore CH4 ,C2H6 and C3H8 are members of a homologous series
