The third homologous series is the cycloalkanes. Their names all end in –ane and begin with cyclo-, for example cyclopropane. The cycloalkanes have the general formula \ ( {C_n} {H_ {2n}}\). Even though they have the same general formula as the alkenes, the cycloalkanes are saturated and contain only single bonds. WebThe double C=C bond is what makes alkenes reactive. It can break open and new atoms can be added across it. Alkenes are not always small molecules. How do you test for an alkene? Alkenes turn bromine water from orange to colourless.

WebAlkenes undergo addition reactions in which atoms of a simple molecule add across the C=C double bond The reaction between bromine and ethene is an example of an addition reaction The same process works for any halogen and any alkene in which the halogen atoms always add to the carbon atoms across the C=C double bond http://www.remondini.net/newsite/?q=system/files/alkene+reactions2.pdf

WebMay 20, 2024 · Alkenes are primarily prepared by elimination reactions of molecules that contain good leaving groups attached to sp 3 carbons. Examples of such reactions are dehydrohalogenations with strong base, and acid-catalyzed dehydrations of alcohols. The opposite of an elimination is an addition reaction. WebAlkenes can react to produce glycols (two adjacent hydroxyl groups) through either an anti- or syn- addition mechanism that is stereospecific. 9.14: Opening of Epoxides - Acidic …
