3.8 I can describe the reaction between alkenes and bromine

1.       Write the word equation showing the reaction between ethene and bromine water
           Ethene + Bromine = 1,2-dibromoethane

2.       Draw the displayed formula of the reaction above

3.       Explain the observations
          Turns brown to colourless liquid
        

        


4.       Why does this reaction not need a catalyst?
          Because the C=C is reactive

5.       What type of reaction is this called?
          Addition Reaction

6.       Explain why this reaction is useful
          It's a chemical test that distinguish saturated and unsaturated hydrocarbons
          (alkanes and alkenes)
