Homologous Series
Chemistry: Edexcel IGCSE, topic 15.2.1
Homologous Series
The homologous series is a series of compounds with the same general formula.
Physical and chemical properties
- The members of the homologous series have similar chemical properties, but the physical properties can change.
- For example, as the carbon chain becomes longer, the boiling point increases.
Molecular formulas
- The molecular formulas of neighbouring compounds differ by a CH2 unit.
