EXPERIMENT 19
Part A: Physical Properties of Hydrocarbons
- Observe the results of the ignition test and record observations in the table below
- Draw the structures of each compound and predict its solubility in water
| Compounds Tested | Structure | Ignition Test | Solubility in Water |
| Methanol | |||
| Acetone | |||
| Hexane | |||
| Cyclohexanol | |||
| Toluene |
Part B: Reaction of Bromine with Hydrocarbons
- Alkenes tend to undergo addition reactions
- We have learned hydrogenation (addition of hydrogen) and hydration (addition of water)
- However, alkenes also undergo halogenation (addition of halogen). Halogenation reaction is exactly like hydrogenation and hydration. Each halogen atom is added to each carbon atom involved in the double bond
- In this video, cyclohexane and cyclohexene are tested using bromine solution. Record observations in the table below

Part 3: KMnO4 Test for Unsaturated Hydrocarbons Potassium Permanganate, KMnO4, is also often used to test for alkenes Alkenes react with KMnO4 to produce a compound with 2 hydroxyl groups (a diol) The color of KMnO4solution is purple. The color of the diol product is colorless. The color of the side product, MnO2, is brown Therefore, we can observe whether a reaction has occured by observing the color of the mixture: If the color after mixing stays purple, that means...
