Homologous series refers to a series of compounds with the same functional group and also similar chemical properties. This series is certainly an important topic within the field of organic chemistry. Students can explore more about it here. Meaning of Homologous Series Detergents. Class 10 Chemistry Carbon and Its Compounds. Homologous Series. Homologous Series. A series of carbon compounds in which same functional group substitutes the hydrogen atom is called a homologous series. These compounds have similar chemical properties due to the addition of same kind of functional group throughout the chain Answer: A homologous series is a series of compounds, which has the same functional group. This also contains similar general formula and chemical properties. Since there is a change in the physical properties, we can say that there would be an increase in the molecular size and mass A homologous series is a series of organic compounds whose members can be denoted by a single general formula and differ from each other by a - C H 2 group. The individual members of a homologous series are called homologue. While transforming a compound into its next homologue, - C H 2 group gets added to the chain

Order in Homologous Series Photograph shows the first members of various homologous series. Alkanes, alkenes, alcohols, carboxylic acids and esters belong to different homologous series. The organisation of organic compounds into the various different homologous series makes the study of organic chemistry more systematic, orderly and effective. The members of any homologous series have. A homologous series is a group or a class of organic compounds having same general formula and similar chemical properties in which the successive members differ by a -CH 2 group. Characteristics of homologous series
Homologous structures can be defined as the organs or skeletal elements of animals and organisms that, by virtue of their similarity, belong to a common ancestor. These structures do not necessarily have to look exactly the same, or have the same function. Analogous structures are similar structures that evolved independently into two living. (c) Homologous series: When the members of a hydrocarbon family obey same general formula they are said to be in homologous series. In this series, members are arranged in increasing order of their molecular masses: Example: Alkane - C n H 2n+2 CH 4 — Methane C 2 H 6 — Ethane C 3 H 8 — Propane C 4 H 10 — Butane. Properties
(a) A homologous series is a group of organic compounds having similar structures and similar chemical properties in which the successive compounds differ by CH 2 group. Example of Homologous series: All the alkanes have similar structures with single covalent bonds and show similar chemical properties, so they can be grouped together in the. a homologous series is a series of compounds with the same general formula, usually varying by a single parameter—such as the length of a carbon chain. Examples of such series are the straight-chained alkanes (paraffins), and some of their derivatives (such as the primary alcohols, aldehydes, and (mono) carboxylic acids) Examples. The homologous series of straight-chained alkanes begins methane (CH 4), ethane (C 2 H 6), propane (C 3 H 8), butane (C 4 H 10), and pentane (C 5 H 12).In that series, successive members differ in mass by an extra methylene bridge (-CH 2 - unit) inserted in the chain. Thus the molecular mass of each member differs by 14 atomic mass units. Adjacent members in such a series, such as. Get a free home demo of LearnNext.

When organic compounds containing same functional group are arranged in series on the basis of their increasing molecular weight, having the difference of -CH 2 (methylene group) in between two consecutive compounds, such series is called homologous series. The individual members of a homologous series are known as homologous and the process is known as homology
A homologous series is a family of hydrocarbons with similar chemical properties who share the same general formula. We will look at three hydrocarbon series: alkanes, alkenes and the cycloalkanes.

(a) Homologous series represent different families of organic compounds into which these are divided. Two characteristics of homologous series are listed. All the members in a particular homologous series of family have the same characteristic functional group. For example, in organic acids, the functional group is carboxyl group (—COOH) Syllabus ref: 10.1. The sheer scale of organic chemistry means that it is important to categorise compounds with similarities in order to make sense of the vast number of organic compounds possible. Categorisation relies on similarities between and within structures, giving rise to the concept of homologous series.
