1) Write the reactions that represent the addition of KMnO 4 and Br 2 to the two alkenes.
2) Draw the full mechanism (with arrow pushing) for the dehydration of tert -amyl alcohol that leads to the formation of both products.
3) Explain the purpose of the following in the above experiment:
a. Sulfuric acid
b. Simple distillation â in step 1
c. Sodium hydroxide extraction
d. Anhydrous sodium sulfate
e. Ice-cooled receiving/collecting flask
f. Covering the flask with a watch glass in step 10
4) Give all possible alkenes formed during the dehydration of each of the following alcohols:
a. 1-methylcyclohexanol
b. 2-methylcyclohexanol
c. cyclopentylmethanol
d. 3,3-dimethyl-1-butanol
5) What alcohol would be the most appropriate starting material for the synthesis of 1- methylcyclohexene? Draw the reaction scheme.
