5. Which of the following are reagents used in the nitration of benzene? Concentrated NO3 Dilute solutions of NO3 and H2SO4 Conc. HNO3 and conc. H2SO4 Ammonia

6. Which of the following is NOT associated with oxidation? PCC LiAlH4 Jones Reagent Hot KMnO4

7. Which of the following will reduce an aldehyde but not a carboxylic acid? NaBH4 H2, Pt catalyst LiAlH4 PCC

8. If branching of the side chain in the product is a problem in Friedel-Crafts alkylation, how can a product with an unbranched side chain be reached?
