Low. Low. • Saturated: all single bonds, Unsaturated: has multiple bonds • Cyclohexane, saturated Cyclohexene,unsaturated • Alkanes: non, alkenes: most *not benzene • a) Orange b) Addition • c) d) Br2 is orange. It (and it’s colour) is used up in the reaction with cycloalkene e) One mole of ethyne
catalyst Cyclohexene + H2SO4 + H2O cyclohexanol Found in water because it can form hydrogen bonds with water (it is polar)
Cyclohexene + KMnO4 + KOH + MnO2 For more lessons, visit www.chalkbored.com
