Flow Chart Showing Tests to Identify All 8 Chemicals Background Information & Methods for Testing: Alkenes5&6: Alkenes are hydrocarbons which are formed by cracking larger hydrocarbons. Unlike alkanes, alkenes are unsaturated due to the double bond between the carbon atoms. They have the general formula CnH2n. An example of an alkene is ethene. It has the structural formula C2H4. Molecular Formula: C2H4 = CH2=CH2 Structural Formula of Ethene: Double bond between Carbon atoms Hydrogen atoms To test for an alkene, I will mix the unknown organic compound with bromine water. The solution will turn from orange to colourless in the presence of an alkene. This will prove that a double bond is present; therefore the liquid was an alkene. The double bond between the carbon atoms will open up and bromine will be added on forming a haloalkane, for example Bromoethane. Add 5cm3 of the unknown liquid into a boiling tube. Then add 2cm3 of Bromine water...
