1. Homologous series

   In 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 unbranched, or differ by molecular formula of CH2 and molecular mass of 14u. This can be the length of a carbon chain, for example in the straight-chained alkanes (paraffins), or it could be the number of monomers in a homopolymer such as amylose.Compounds within a homologous series typically have a fixed set of functional groups that gives them similar chemical and physical properties. (For example, the series of primary straight-chained alcohols has a hydroxyl at the end of the carbon chain.) These properties typically change gradually along the series, and the changes can often be explained by mere differences in molecular size and mass. The name "homologous series" is also often used for any collection of compounds that have similar structures or include the same functional group, such as the general alkanes (straight and branched), the alkenes (olefins), the carbohydrates, etc. However, if the members cannot be arranged in a linear order by a single parameter, the collection may be better called a "chemical family" or "class of homologous compounds" than a "series". The concept of homologous series was proposed in 1843 by the French chemist Charles Gerhardt. A homologation reaction is a chemical process that converts one member of a homologous series to the next member.

1. Homologous series

   In chemistry, a homologous series is a series of compounds with a similar 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, and some of their derivatives. The single-ring unbranched cycloalkanes form another such series. Compounds within a homologous series typically have a fixed set of functional groups that gives them similar chemical and physical properties. These properties typically change gradually along the series, and the changes can often be explained by mere differences in molecular size and mass. The name "homologous series" is also often used for any collection of compounds that have similar structures or include the same functional group, such as the general alkanes, the alkenes, the carbohydrates, etc. However, if the members cannot be arranged in a linear order by a single parameter, the collection may be better called a "chemical family" or "class of homologous compounds" than a "series".
