5. Which description below best describes the role of concentrated sulfuric acid in nitration reactions of aromatic rings?



It activates the aromatic ring allowing nitration to occur more readily

6. When concentrated sulfuric acid reacts with concentrated nitric acid the two products are the unstable ion and .

7. What temperature range is typically used to ensure the formation of mononitration of benzene?




8. If the nitration reaction of benzene is carried out at high temperatures then this will result in the formation of -nitrated molecules.

9. Which ion is likely to act as a base and remove a proton (H+) from the intermediate arenium ion?




Poly-nitrated aromatic compounds are often used as explosives, classroon explosion.

11. What is the name of the resonance stabilised intermediate ion formed during nitration of aromatic rings?




12. The common feature present in all aromatic molecules that allows them to react with electrophiles is the presence of electrons which form areas or orbitals of high density above and below the flat planar aromatic rings.
