Which compound belongs to a homologous series?
Which compound belongs to a homologous series?
- A compound with no functional group
- A compound with the same functional group but different chemical properties
- A compound with completely different functional group and chemical properties
- A compound with the same functional group and similar chemical properties as other members of the series (correct)
What defines compounds within a homologous series?
What defines compounds within a homologous series?
- A fixed set of functional groups giving them similar chemical and physical properties (correct)
- No fixed functional groups, resulting in random chemical and physical properties
- A single functional group with identical chemical but different physical properties
- A wide variety of functional groups giving them diverse chemical and physical properties

Study Notes
Homologous Series
- A compound belongs to a homologous series if it has the same functional group and similar chemical properties, but differs from others in the series by a –CH2– group.
- Compounds within a homologous series are defined by having the same functional group, same chemical properties, and differing only by a –CH2– group.
- In 1843, Charles Gerhardt proposed the concept of homologous series.
Properties of Compounds in a Homologous Series
- The properties of compounds in a homologous series typically change in a gradual and predictable manner as the molecular formula changes.
Chemical Family
- A collection of compounds is better called a 'chemical family' or 'class of homologous compounds' when they share the same functional group and similar chemical properties.
