1. Chemical Reactions of Alkanes and Alkenes

2. Structure cyclohexane cyclohexene

3. CyclohexeneCyclohexane BrownPurple after Purple KMnO 4 before ColourlessOrange after Orange Br 2 before Cloudy, warmNo reaction H 2 SO 4 & H 2 O insoluble Solubility

4. 1.Low. Low. 2.Saturated: all single bonds, Unsaturated: has multiple bonds 3.Cyclohexane, saturated Cyclohexene, unsaturated 4.Alkanes: non, alkenes: most *not benzene 5.a) Orange b) Addition c) d) Br 2 is orange. It (and its colour) is used up in the reaction with cycloalkene e) One mole of ethyne

5. Cyclohexene + H 2 SO 4 + H 2 O cyclohexanol Found in water because it can form hydrogen bonds with water (it is polar) catalyst

6. Cyclohexene + KMnO 4 + KOH + MnO 2 For more lessons, visit www.chalkbored.com www.chalkbored.com
