This lesson allows the students to see that ALL electrophilic substitution reactions of benzene progress by the same mechanism: 1 - formation of the electrophile in situ; 2 - attack of the electrophile on the ring; 3 - reformation of the catalyst. 6.1.1 (d) The electrophilic substitution of aromatic compounds with: (i) concentrated nitric acid in the presence of concentrated sulfuric acid (ii) a halogen in the presence of a halogen carrier

This lesson looks at how scientific knowledge develops over time as more evidence becomes available. It is also a chance to review the shapes of atomic orbitals as it builds on knowledge of side-on overlap of the p-orbitals to form the delocalised pi ring of electrons. Students meet the arenes in year 12, but only in passing, so they will have little idea as to the molecular and structural formula of benzene.
