Answer

  1. Compounds with same functional group substitutes for hydrogen in a carbon chain.

Explanation:

A homologous series is a series of compounds with the same general formula.

But they have different melting points (physical properties) and different molecular masses. However, they have the same functional group substitutes for hydrogen in a carbon chain.

Example: CH3​OH, C2​H5​OH, C3​H7​OH.
