Journal of the American Chemical Society Find more information about Crossref citation counts. Example: The homologous series of straight chain alkanes can be represented by the general formula C n H 2 n + 2 Thus the first four members of alkane homologous series are C H 4 (methane), C H 3 − C H 3 (Ethane), C H 3 − C H 2 − C H 3 (propane) and C H 3 − C H 2 − C H 2 − C H 3 (butane). Relations between molecular volume and structure of hydrocarbons at 20.deg.. Computation of equilibrium constants for multicomponent systems from spectrophotometric data. Masaaki Satou, Hirofumi Nemoto, Susumu Yokoyama, and Yuzo Sanada. In lieu of an abstract, this is the article's first page. The alkanes, alkenes and cycloalkanes are examples of homologous series. Methane, ethane, propane, butane and so on is a homologous series. Please reconnect. My Activity. Find more information about Crossref citation counts. The alkanes are saturated because they only contain single bonds. formula of C (2)H (2n+2) where n=number of carbons. A homologous series is a family of hydrocarbons with similar chemical properties who share the same general formula. Calculation of Weight Per Cent Ring and Number of Rings per Molecule for Aromatics. Alkenes can be used as fuels, solvents and starting materials for everyday products such as plastics and alcohol. Because of the non-polar nature of alkanes, they are relatively unreactive; one important exception is combustion with oxygen. The alkenes are unsaturated. In the structural formula the carbon-carbon double bond is represented by two lines between the two carbon atoms. Homologous series of alkanes. A. Grigor’ev. A homologous series is a group of chemicals which have similar chemical properties and can be represented by a general formula. • Naming alkenes has the same rules as alkanes. Alkane molecules can be represented by displayed formulae in which each atom is shown as its symbol (C or H) and the covalent bonds between them by a straight line. Alkanes are considered a homologous series because each subsequent alkane differs only by the addition of one carbon and two hydrogens. Alkenes all contain a carbon to carbon double bond which makes them more reactive than the alkanes. The straight chain alkanes share the same general formula: The general formula means that the number of hydrogen atoms in an alkane is double the number of carbon atoms, plus two.
