The first lower member like ethene, propene and butene are colorless gases. Alkenes with five to fifteen carbon atoms are liquids and higher ones are solids at ordinary temperatures. Alkenes have characteristic smel..

Lower alkenes are mixed with air and passed under pressure over a silver catalyst at 200-400°C. This gives epoxides by adding one atom of oxygen across the double bond. The epoxides so obtained are used in detergents. ethene ..

This method involves heating of excess of primary alcohol with concentrated sulphuric acid at 413 K to get symmetrical ether. The formation of reaction product, alkene or ether depends on the reaction conditions. In this reaction alcohol has to be used in excess and the temperat..

Vicinal dihaloalkanes are those dihalogen derivatives of alkanes in which two halogen atoms are on the adjacent carbon atoms. Alkenes can be obtained from vicinal dihaloalkanes by dehalogenation. When such a dihaloalkane is heated with zinc in methanol, an alkene is formed. ..
