Homologous series - Wikipedia, the free encyclopedia
In chemistry, a homologous series is a series of organic compounds with a similar general formula, possessing similar chemical properties due to the presence of the same functional group, and shows ...

A series of organic compounds that have similar structural features but differ from adjacent members by (-CH2) group is referred to as homologous series. ...

All the members of a homologous series can be represented by a common general formula, as they have the same functional group. For example, alkanes can be represented by the formula CnH2n+2.

These are groups of atoms or bonds common to a series or family of compounds and which decide the principal chemical properties of the series. Such a series is called a Homologous Series, and can be represented by a general formula.

Definition of Homolog (homologue; homologous; homologous series) ... homolog (homologue; homologous; homologous series); A compound belonging to a series of compounds that differ by a repeating group. For example, propanol (CH3CH2CH2OH), n-butanol (CH3CH2CH2CH2OH), and n-pentanol (CH3CH2CH2CH2CH2OH) are homologs;

The general formula for alkanes is CnH2n + 2. Subsets of the alkenes (olefins) and alkynes (acetylenes) also form homologous series. With only a single instance of the defining double or triple bond, respectively, they will also gain 14 mass units with every new CH2 group introduced.
