Which reagents/catalysts would be needed to convert benzene to p-bromonitrobenzene?

Question

Quizplus · Accepted Answer

Both reagents/catalysts given in choices A and B are necessary for the conversion of benzene to p-bromonitrobenzene. The first one, Br2/FeBr3, is used to brominate the benzene ring, and the second one, HNO3/H2SO4, is used to nitrate the brominated benzene ring. NaOH (choice C) is a base and would not contribute to the desired reaction. HS2O3/sulfurous acid and heat (choice D) may be used to reduce or remove the nitro group, rather than add a bromine atom.
