What is homologous series of hydrocarbons explain with example?
Example of Homologous series : All the alkanes have similar structures with single covalent bonds and show similar chemical properties, so they can be grouped together in the form of a homologous series. Homologous series of alkanes : Methane, CH4; Ethane, C2H6; Propane, C3H8; Butane, C4H10; Pentane, C5H12
What is the homologous series of alkanes?
The alkanes are a homologous series of hydrocarbons . This means that they have similar chemical properties to each other and they have trends in physical properties. For example, as the chain length increases, their boiling point increases.
What is a homologous series of compounds?
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 -CH2. The concept of homologous series was proposed in 1843 by the French chemist Charles Gerhardt.
What is the characteristics of hydrocarbons of the same homologous series?
The members of the homologous series have same functional group. Members have the same general formula. Members have the almost same chemical properties due to same functional group. Members have common general method of preparation.
What is homologous series Class 10?
> A homologous series is a series of hydrocarbons which have similar chemical properties and they share the same general formula. They are organic compounds having similar structure and functional groups. – They contain the same functional group throughout the series.
What is homologous series Class 11?
A homologous series is defined as a family or group of structurally similar organic compounds all the members of which contain the same functional group, Show a gradation in physical and similarity in chemical properties and any two adjacent members of which differ by a -CH2 group.
Is hexane homologous series?
Each successive molecule in the alkane homologous series is formed by adding a carbon and two hydrogen atoms or a CH2 (methylene group) to the previous molecule….Alkane Homologous Series.
| Name | Hexane |
|---|---|
| Number of Carbon atoms | 6 |
| Molecular Formula CnH2n+2 | C6H2(6)+2 = C6H1 |
| Boiling Point °C | 69 |
| Melting Point °C | −95 |
Which is the homologous series?
A homologous series is a family of hydrocarbons with similar chemical properties who share the same general formula. We will look at three hydrocarbon series: alkanes, alkenes and the cycloalkanes. Hydrocarbons are compounds that contain only hydrogen and carbon.
What is properties homologous series?
A Homologous Series is a group of organic chemical compounds, usually listed in order of increasing size, that have a similar structure (and hence, also similar properties) and whose structures differ only by the number of CH2 units in the main carbon chain.
What is homologous series?
A homologous series is a series of compounds with the same general formula, usually varying by a single parameter such as the length of a carbon chain. Compounds within a homologous series typically have a fixed set of functional groups that gives them similar chemical and physical properties.
What is called homologous series and its characteristics?
Homologous series is a series of compounds with similar chemical properties and the same functional group differing from the successive member by −CH2. Example: The homologous series of straight-chain alkanes can be represented by the general formula CnH2n+2.
What is homologous series of carbon compounds?
The series of carbon compounds in which two successive compounds differ by –CH 2 unit is called homologous series. Eg: 1) CH 4, C 2 H 6, C 3 H 8 … 2) CH 3 OH, C 2 H 5 OH, C 3 H 7 OH … If you observe above series of compounds, you will notice that each compound in the series differs by –CH 2 unit by its successive compound.
What is the homologous series of aliphatic hydrocarbon?
The alkanes are a homologous series of aliphatic hydrocarbons. The first and simplest homologue of this series is methane, CH_4; thus sometime it is called as methane series. The second alkane is ethane, C_2H_6, and the third is propane, C_3H_8.
Homologous series is a series of compounds with similar chemical properties and same functional group differing from the successive member by CH 2. Carbon chains of varying length have been observed in organic compounds having the same general formula. Such organic compounds that vary from one another by…
