Homologous Series
Easychemistry
Members of a homologous series differ by:
Select the correct option:
Solution
Incorrect! Answer:
-CH₂- unit
A Homologous Series is a group of organic compounds having the same functional group and similar chemical properties.
- Successive members differ by a Methylene group (−CH2−) unit.
- This difference leads to a difference in molecular mass of 14 u (12+2×1).
- Regular progression in physical properties (like boiling point) is observed as the chain length increases within the series.
