What is an homologous series? Explain with an example.
What is an homologous series? Explain with an example. A homologous series is a group of compounds with similar chemical properties and a gradual increase in molecular weight. Example: Alkanes (saturated hydrocarbons) – methane (CH4), ethane (C2H6), propane (C3H8), and so on. Each member differs by a -CH2- group. Explore Entire Collection of Texcellency Books
