What is an homologous series? Explain with an example

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.

Final answer: 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.
