Ans:
Homologous Series:
A series of organic compounds with the same general formula but differ from adjacent members by "-CH2-" group are referred to as homologous series of compounds.
And successive members of homologous series differ from one another in their mass by 14 units.

Molecules in homologous series:

FormulaName of the molecule C3H4 Propyne C4H6 Butyne C5H8 Pentyne

Molecules in homologous series:

FormulaName of the molecule C3H6 Propene C4H8 Butene C5H10 Pentene
