Sample Question
Describe the features of a homologous series.

Homologous series do not exhibit any similarities in chemical properties and physical properties.

Include the same general formula, neighbouring members differing by CH2, similar chemical properties and gradation in physical properties. Homologous series: A series of compounds (usually hydrocarbons) that display similar chemical properties and functional groups but different physical properties (generally boiling point), often differing by one repeating unit, usually a CH2/CH3 molecule. They can be given a general formula, eg CnH2n+2 Organic chemistry is the chemistry of carbon compounds (excluding compounds such as metal carbonates and oxides). The ability of carbon atoms to form chains leads to the existence of a series of compounds that have the same functional group (and hence similar chemical properties) and only differ from each other by the presence of an additional carbon atom and its two associated hydrogen atoms in the molecule (which causes the physical properties to change in a regular manner).

Homologous series do not have a general formula and do not show gradation in physical properties.

Homologous series consist of compounds that have completely different chemical properties and functional groups.
