5 Questions
Which compound belongs to a homologous series?
A compound with the same functional group and similar chemical properties as other members of the series
What defines compounds within a homologous series?
A fixed set of functional groups giving them similar chemical and physical properties
What did Charles Gerhardt propose in 1843?
The concept of homologous series
How do the properties of compounds in a homologous series typically change?
Gradually along the series, often explained by differences in molecular size and mass
When is a collection of compounds better called a 'chemical family' or 'class of homologous compounds'?
When the members cannot be arranged in a linear order by a single parameter
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.
