First, the learning unit describes the mechanism of electrophilic aromatic substitution including the energetics, intermediates, and transition states. Further, it is discussed in which way the inductive and mesomeric effects of first substituents influence the reactivity of substituted aromatic compounds in second substitution. Then, the nucleophilic aromatic substitution's mechanism is explained inclusive of intermediates, transition states, etc.. Finally, the preparation and the structure of dehydroarenes (arynes) is depicted.
