What does it look like when an alkene reacts and undergoes an addition reaction? View the video “Double Bonds” to find out. As you watch the video, carefully observe changes that occur to the substances involved.

 

Use the results of the test performed at the end of the video to answer Try This questions 3–6.

Addition Reactions

 

 

TR 3. Prepare a data table for the tests performed during the investigation “Double Bonds.”

 

TR 4. Write the balanced chemical equation for the reaction between cyclohexene and bromine.

 

TR 5. Which substance, corn oil or octane, contains double bonds? Use the evidence from the investigation to support your answer.

 

TR 6. Fats that contain double bonds are often called unsaturated fats. A common test to determine the extent of the unsaturation is to perform a titration using the halogen iodine. It is observed that a 1:1 mole ratio exists between the moles of iodine that will react to the moles of double bonds in the fat. Explain why such a relationship is observed.
