Example of Lab Report (Experiment 4)
Conclusion:
Cyclohexane and toluene undergoes free radical substitution reaction with bromine in the presence of sunlight.
Cyclohexene undergoes electrophilic addition reaction with bromine with and without sunlight.
Cyclohexene can be oxidized by Baeyer's Test (dilute, cold alkaline potassium permanganate).
Baeyer's test can be used to differentiate an alkane, alkene and arene.
Bromine test in the dark can be used to differentiate alkene from alkane.
