You are asked to synthesize each of the molecules below starting with benzene and any other reagents you need. Using the reagents listed on the Reagent Table, write the corresponding letter designations from the reagent sheet of the reagents you would use (in conjunction with benzene) in the order you would use them to synthesize each (separate each with a comma if it takes more than one reagent to effect the synthesis.) Assume you can heat up or cool down the reaction flask as needed for the reaction to proceed with practical rates even if no temperature is indicated in the table. a) Propylbenzene b) Bromobenzene
