A series of compounds in which adjacent members of the series differ by a fixed unit of structure.
a series of similar compounds that conform to a general formula; a series of organic compounds which differ from each other by a specific structural unit; there is a constant increment of change in molecular structure from one compound in the series to the next.
A series of similar organic compounds, differing only in that the next higher member of the series has an additional CH2 group (one carbon atom and two hydrogen atoms) in its molecular structure. Fuel oils are characterised by the presence of an identifiable homologous series of normal alkanes.
a family of compounds which have a general formula and have similar chemical properties
a group of compounds which have the same functional group or groups but different chain lengths or ring sizes, Sir
a group of molecules with the same general formula and the same functional group
a group of organic compounds with similar chemical properties and structural formula and a gradual change in physical properties e
a set of compounds whose components differ by a single repeating functional group
A series of compounds, all members of which contain the same functional group, and successive members differ by CH2.
A series of compounds in which each member differs from the next by a specific number and kind of atoms.
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 gradation in physical properties as a result of increase in molecular size and mass (see relative molecular mass). For example, ethane has a higher boiling point than methane since it has more Van der Waals forces with neighbouring molecules. This is due to the increase in the number of atoms making up the molecule.
