(10 pts) Consider this reaction: CsHo + 2 Brz → FeBro p.dibromobenzene 5.0 mL of benzene (MW 78, density = 0.88 g/ml) are reacted with 5.0 mL of Bra (MW 160, density 3.1 g/mL); 9.54 g of p-dibromobenzene (MW 236) are produced. What is the percent yield? Show your work clearly. 7. (11 pts) When you are done with this written exam, wait in the hall. Eventually you as an individual will be asked to go into the lab and set up one of the following apparatuses Simple distillation Vacuum filtration Reflux Reflux with addition as we used for the Grignard
