Tyrocity.com envisions the education system of the country to be redefined through active engagement, discussions, required assistance and by bringing the right information to your fingertips. For Ex:The functional group of alcohols is the hydroxyl group i.e. 2) All the members of a given homologous series possess the same functional group. 2. 4. Each member of a homologous series is known as homologue and this phenomenon is called homology. Organic Chemistry - Some Basic Principles and Techniques, Economics Chapter 1 Development – Notes & Study Material, Geography Chapter 6 Manufacturing Industries – Notes & Study Material. The members of a homologous series can be represented by same general formula. OH , we get a new homologous series. Their condensed structural formulas are given below: Methane - CH4 The general formula of this homologous series is CnH2n+1OH. This homologous series is called, The general formula of this homologous series is C, 3) The successive members of a homologous series differ by a -CH. 2. 1) Each homologous series can be represented by a general formula. Homologous series is the characteristic feature of carbon compounds in which carbon and hydrogen atoms in hydrocarbons varying by single parameter. (iii) Their physical properties such as melting point, boiling point, density, generally show a gradual change with increase of molecular formula in the series. The members of a series have same functional group. Filed Under: Chemistry, Class 11, Organic Chemistry - Some Basic Principles and Techniques Tagged With: characteristics of homologous series, homologous series, homologues, homology. Homologous Series and its Characteristics with Examples - … (ii) They have the same functional group. All the organic compounds have been divided into different families or group depending upon their structure and chemical properties. 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 - CH2 group.

The members of a particular homologous series have almost same chemical properties due to presence of same functional group. The first member of homologous series generally shows certain different chemical behavior than other members of the series. Four characteristics of a homologous series are: (i) The general formula of all compounds in the series is the same. 6. 6) The chemical properties of the members of homologous series are similar though the first member may vary considerably from rest of the members.
