Question

what is homologous series explain with an example answer in maximum 50 world

Answer 1

In organic chemistry, a homologous series is a series of compounds with the same functional group and similar chemical properties in which the members of the series differ by the number of repeating units they contain.[1] This can be the length of a carbon chain,[1] for example in the straight-chained alkanes (paraffins), or it could be the number of monomers in a homopolymer such as amylose.[2]..
Hope it's helps u ❤️✌️✌️


Compounds within a homologous series typically have a fixed set of functional groupsthat gives them similar chemical and physical properties. (For example, the series of primary straight-chained alcohols has an 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.[3] A homologation reactionis a chemical process that converts one member of a homologous series to the next member.

Answer 2

these are the series of compounds with same functional grp, same chemical and physical properties same no. of carbon but differ in ch3 grp
eg methane ,ethane, propane etc
