Answer

  1. A series of compounds in which the same functional group substitutes for hydrogen in a carbon chain.

Explanation:

Homologous series is a series of compounds in which the same functional group substitutes for hydrogen in a carbon chain. The chemical properties of the compounds are very similar.

Example of a homologous series: CH3​OH,C2​H5​OH,C3​H7​OH,C4​H9​OH.
