In organic chemistry, an alkene, olefin, or olefine is an unsaturated chemical compound containing at least one carbon-to-carbon double bond. Alkenes. Although there are similarities between alkanes and alkenes such as … While it might look like it contains carbon-carbon double bonds, the real structure of benzene is slightly more complicated. The characteristic feature of alkenes is the presence of a carbon-carbon double bond. compds. Hydrogenation . Alkenes and alkynes are called unsaturated hydrocarbons because, as the name indicates, the carbon atoms are not "saturated" with hydrogens, owing to the presence of double or triple carbon-carbon bonds. The general formula for alkene containing one double bond is C n H 2n. Ethene C2H4 2. contain 10 carbon atoms. 1. The simplest alkene with one double bond is ethene. Alkenes bear the general formula CnH2n. If you know how to name alkanes, adding alkene nomenclature to your repertoire is a fairly straightforward task. Alkanes: Alkanes have no pi bonds. Whereas the names of alkanes end with the suffix –ane, alkenes end with the suffix –ene.A two-carbon alkene, therefore, is named ethene; a three-carbon alkene is named propene, and an alkene in a five-membered ring is named cyclopentene, as shown here. 10 . Similarly, propene is used in the manufacture of polypropene. Click HERE for my FREE Alkene Reactions Practice Quiz. Alkenes: Alkenes can undergo polymerization. Alkenes are hydrocarbons that contain a carbon-carbon double bond, whereas alkynes have a carbon-carbon triple bond. Alkenes are a homologous series of compounds have the general formula: CnH2n. When you see an alkene like this, you start numbering closest to the double bond, just like as if it was a alkyl group, as if it was a side chain of carbons. Alkanes, alkenes, and alkynes are similar in name but they are slightly different. These polymers are used in making plastic bags, pipes electrical insulation, etc. Alkenes are defined by the carbon-to-carbon double bond, and it is this bond that is responsible for many of the specific properties of the alkenes. A family of compounds that grows in such a way is called a homologous series. The alkenes comprise a series of compounds that are composed of carbon and hydrogen atoms with at least one double bond in the carbon chain. Pi Bonds. Its molecules. The double bond is between two and three, and to specify its location, you start at the lowest of these numbers. Butene C4H8 4. By Arthur Winter . Ethene is used in the preparation of solvents like ethylene glycol, dioxane, etc. This group of compounds comprises a homologous series with a general molecular formula of C n H 2 n, where n equals any integer greater than one. Other articles where Alkyne is discussed: hydrocarbon: Alkenes and alkynes: Alkenes (also called olefins) and alkynes (also called acetylenes) belong to the class of unsaturated aliphatic hydrocarbons. Organic chemistry is the study of carbon compounds, so the study of organic chemistry is important because all living things are based on carbon compounds. What are synonyms for Alkenes? The presence of weak π bond makes alkenes somewhat less stable compounds in comparison to alkanes. Alkenes and Olefins. Key Takeaway • Alkenes are hydrocarbons with a carbon-to-carbon double bond. Propene C3H6 3. Eventhough the use of them may overlaps in some cases, each of them is a compound on their own.
