Hii. l hope I help you please mark brainlist
Explanation:
A homologous series is a series of compounds with the same general formula, usually varying by a single parameter such as the length of a carbon chain. Compounds within a homologous series typically have a fixed set of functional groups that gives them similar chemical and physical properties.
For example, methane, ethane, propane, butane, etc. are all part of the alkane homologous series. The general formula of this series is C

Answer:
A homologous series is a family of hydrocarbons with similar chemical properties who share the same general formula. We will look at three hydrocarbon series: alkanes, alkenes and the cycloalkanes. Hydrocarbons are compounds that contain only hydrogen and carbon.
