An homologous series is a group of compounds with similar structural features that can be represented by a general formula whose members differ by one ch 2 unit. Carbon chains of varying length have been observed in organic compounds having the same general formula. What is the general formula of the homologous series of. The general formula for the homologous series of alcohols is. In chemistry, a homologous series is a series of organic compounds with a similar general formula, possessing similar chemical properties due. Alcohols alcohols and carboxylic acids edexcel gcse. Homologous series is a series of compounds with similar chemical properties and same functional group differing from the successive member by ch 2. Carboxylic acids is a homologous series in which the compounds contain a functional. Homologous series of alkanes, alkenes and alkynes with. An example of an alcohol and an alkanol is shown here. Naming and drawing including shortened structural formula for straight chain alcohols.
If you know the answer to this question, please register to. Number the carbon atoms in the chain so that the functional group in this case, the hydroxyl group has the lowest possible number. The singlering cycloalkanes form another such series, starting with cyclopropane.
