homologous series example

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. Homologous series 1. There are a number of homologous series in organic compounds. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. Members of the same homologous series can be prepared through one common method. Looks like you’ve clipped this slide to already. The alkanes family is a homologous family which have linear molecules. This also contains similar general formula and chemical properties. Example: Alkane / Alkene / Alkyne / Alcohol. homologous series. In the above three series, each member differs from its proceeding member by a CH 2 unit. A series of compounds with similar chemical properties, in which members differ from one another by additional CH2 group, is called a homologous series. Answer. Similarly the series of alkene and alkynes also forms homologous series. Homologous series of alkenes are as follows: Homologous series of alkynes are as follows: Class 10 Chemistry Carbon and Its Compounds.

For example: The homologous series of alcohols (class) contains the hydroxyl functional group. Alkanes, alkenes and alkynes are some examples for this series. This also contains similar general formula and chemical properties. But the chemical properties of a homologous series determined by the functional group remain same. The series like methanol, ethanol, propanol, butanol and so on is also a homologous series. 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. Clipping is a handy way to collect important slides you want to go back to later. 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. Departament d'Educació - Generalitat de Catalunya, No public clipboards found for this slide, Science Teacher at Jose Marti Technical High School. Homologous Series. Learn more. It can be noticed that there is a difference of −CH2 unit between each successive compound. A series of compounds in which the same functional group substitutes for hydrogen in a carbon chain is called a homologous series. Methane, ethane, propane, butane and so on is a homologous series. The functional group attached to these compounds is alcohol. zoom id - 309 672 8037 passcode - 12 please join​, 1. A series of carbon compounds in which same functional group substitutes the hydrogen atom is called a homologous series. Give one example. A homologous series is a series of compounds, which has the same functional group. For example, the series of alkanes i.e. You can change your ad preferences anytime. Methane, ethane, propane, butane and so on is a homologous series. Figure 02: Boiling Points Gradually Change in a Homologous Series Typically, the members of a homologous series contain a fixed set of functional groups that give these molecules similar chemical and physical properties.

For example, a homologous series of straight-chain alkanes begin with methane, ethane propane, butane and pentane. A series of compounds where each consecutive member differs from one particular unit is called 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.  A series of compounds with similar chemical Give reasons(i) why did Rutherford predict electrons revolve aroundthe nucleus of atom? The alkanes, alkenes and cycloalkanes are examples of homologous series. Now customize the name of a clipboard to store your clips. Examples: Ethane C 2 H 6, Propane C 3 … Similarly the series of alkene and alkynes also forms homologous series. Members of the homologous series are called homologs. 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. Since there is a change in the physical properties, we can say that there would be an increase in the molecular size and mass. 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' 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.
