Benzene reacts with bromine.

a. Write a balanced chemical equation for this reaction.

b. Name the catalyst used.

c. What visual observations could be made during the reaction?

d. Benzene will also react with halogenoalkanes. This is called a Friedel–Crafts reaction.

i. Using 1-chloropropane, write the formula of the catalyst needed to start the reaction with benzene.

ii. Write the structural formula of the electrophile in this Friedel–Crafts reaction.

iii. Name the organic product of this reaction.

iv. There are three steps in the mechanism of this Friedel–Crafts reaction. Draw the three steps in the mechanism to show the formation of the electrophile, the attack on the benzene ring by the electrophile and the formation of the products of the reaction (to include the regeneration of the catalyst).
