What is a homologous series of carbon compounds ? If you continue browsing the site, you agree to the use of cookies on this website. In the above three series, each member differs from its proceeding member by a CH 2 unit. The series like methanol, ethanol, propanol, butanol and so on is also a homologous series. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. Lets take a brief look at the homologous series of alkanes for example. The difference between two consecutive members in their composition is –CH 2 unit. See our Privacy Policy and User Agreement for details. zoom id - 309 672 8037 passcode - 12 please join​, 1. These compounds have similar chemical properties due to the addition of same kind of functional group throughout the chain. You can tell that all the molecules in the series (from methane to pentane) have the same general formula: Furthermore, from methane to ethane and from ethane to propane (i.e. As of this date, Scribd will manage your SlideShare account and any content you may have on SlideShare, and Scribd's General Terms of Use and Privacy Policy will apply. The alkanes family is a homologous family which have linear molecules. What is Homologous series. This also contains similar general formula and chemical properties. For example, the series of alkanes i.e. A series of compounds where each consecutive member differs from one particular unit is called a homologous series. top. The alkanes, alkenes and cycloalkanes are examples of homologous series. Homologous Series 2. The general formula of this series is CnH2n+2. But the chemical properties of a homologous series determined by the functional group remain same.

A general formula is one in which the numbers of carbons are represented by the letter 'n' and the numbers of other elements as a function of 'n' Methane, ethane, propane, butane and so on is a homologous series. With the increase in molecular mass in a homologous series the physical properties like melting points, boiling points and solubility in a particular solvent increases. Common examples of homologous structures are the bones in the forelimbs of various vertebrates, such as humans, dogs, birds and whales. Dr James Chemistry SPM Form 5 Chapter 2 Carbon Compounds. homologous series. A homologous series is a series of compounds, which has the same functional group. Clipping is a handy way to collect important slides you want to go back to later. Give an example and list its three characteristics. consecutive members of the series… It can be noticed that there is a difference of −CH2 unit between each successive compound. Example: Alkane / Alkene / Alkyne / Alcohol. Since there is a change in the physical properties, we can say that there would be an increase in the molecular size and mass.

Similarly the series of alkene and alkynes also forms homologous series. another by additional CH2 group, is called a A series of compounds with similar chemical properties, in which members differ from one another by additional CH2 group, is called a homologous series. …, What term did Mendel use for genes? Homologous series of alkenes are as follows: Homologous series of alkynes are as follows: Class 10 Chemistry Carbon and Its Compounds. Alcohols (R – OH), Aldehydes (R – CHO), Carboxylic acid (R – COOH), Ketones(R-C(=O)-R') are some of homologous series and their general formulae. Some important series of aliphatic compounds are listed below: If we examine the unbranched alkanes, we notice that each alkane differs from the preceding alkane by one —CH 2 — group. Homologous series 1. Similarly the series of alkene and alkynes also forms homologous series. Homologous Series. For example, the series of alkanes i.e. (i) Why did Rutherford predict there is large empty spacewit Examples: Ethane C 2 H 6, Propane C 3 … Give reasons(i) why did Rutherford predict electrons revolve aroundthe nucleus of atom? A series of carbon compounds in which same functional group substitutes the hydrogen atom is called a homologous series. Examples:- You can change your ad preferences anytime. Members of the same homologous series can be prepared through one common method. Since there is a change in the physical properties, we can say that there would be an increase in the molecular size and mass. If you wish to opt out, please close your SlideShare account. This site is using cookies under cookie policy. Alkanes, alkenes and alkynes are some examples for this series. Methane, ethane, propane, butane, etc.  A series of compounds with similar chemical 1. Homologous series is defined as a systematic order of organic compounds having same functional group that can be represented by same general formula and prepared by same method. Methane, ethane, propane, butane and so on is a homologous series.
