Their study becomes easier and since they have similar reactions we can find out the reaction of the whole series by just studying the reaction of one of the compounds. The general formula of … Characteristics Of Homologous Series Structure of diamond and graphite using vsepr theory. (2 or 3 marks), mam/sir, I made one formula to find the number of covalent bonds between the hydrocarbon so please will you tell me that it really works or not. Afraid of a subject or a topic? Explain how the fullerenes can be made good conductor of electricity, How can we easily remember the Naming of carbon compond, lewis dot structure and explanation of H2SO4 and CO, Show me the electron dot structure of CH2(Methylene).Also show the bonding. A series of organic compounds that have similar structural features but differ from adjacent members by (-CH2) group is referred to as homologous series. CH3-OH, CH3-CH2-OH, C3H7-OH are the members of a homologous series called "Alcohols". Can you pls give me the definition of butane ring..Where it is used? Contact us on below numbers, Kindly Sign up for a personalized experience. a group of organic compounds (compounds that contain C atoms) that differ from each other by one methylene (CH2 ) group For example, methane, ethane, propane, butane, etc. It saves time. A series of organic compounds that have similar structural features but differ from adjacent members by (-CH, If the propertie of one member of the series is known then we can predict the properties of other member of the series. Don’t worry, let us know and we will help you master it. What is the importance of homologous series. Chemical properties of the members of a homologous series are the same due to the fact that they all have the same functional groups in them. Queries asked on Sunday & after 7pm from Monday to Saturday will be answered after 12pm the next working day. It helps to predict properties of even those members of a series which are not yet prepared. Each member of homologous series is called homolog. Nature of members of a family can be predicted by knowing properties of a first few members. All rights reserved. In the field of organic chemistry, a homologous series is a sequence of compounds with the same functional group and similar chemical properties in which the members of the series can be branched or … Verify your number to create your account, Sign up with different email address/mobile number, NEWSLETTER : Get latest updates in your inbox, Need assistance? A mixture of O2 and ethyne is used for welding purpose. It helps for systematic study of organic compounds. This series has enabled scientists and engineers to study different organic compounds systematically. Respected Mam/Sir Copyright © 2020 Applect Learning Systems Pvt. Carbon and Its Compounds, Introduction to Hydrocarbons. increasing boiling points). Similar properties are shown by homologous series. 1. are all part of the alkane homologous series. Other homologous series include the alkenes, CnH2n, the alkanols, CnH2n+1 OH, and the carboxylic acids, CnH2n+1 COOH. Copyright Notice © 2020 Greycells18 Media Limited and its licensors. Is it neccesary to use it or is there any other way other than using it? Nature of members of a family can be predicted by knowing properties of a first few members. Can you tell why a mixture of ethyne and air is not used? A homologous series (homos is Greek for “the same as”) can be defined as the group of compounds in which the various members have similar structural features and similar chemical properties and the successive members differ in their molecular formula by one methylene (CH 2) group. Want a call from us give your mobile number below, For any content/service related issues please contact on this number. A homologous series is a family of organic compounds which follows a regular structural pattern, in which each successive member differs in its molecular formula by a –CH2 – group. Ltd. All rights reserved. A homologous series is a group of compounds with similar characteristics and the same general formula. Chemicals in the same homologous series will show a gradual variation in one property (eg. Explain the concept of tetravalency, catenation. A homologous series is a series of carbon compounds that have different numbers of carbon atoms but contain the same functional group. Some examples of homologous series are shown in the following table: alkanes, alkenes, alcohols, carboxylic acids.
