Substituents on an aromatic ring can have several effects on electrophilic aromatic substitution reactions. Substituents can activate or deactivate the ring to substitution, donate or withdraw electrons inductively, donate or withdraw electrons through resonance, and direct substitution either to the ortho/para or to the meta positions. From the lists of substituents, select the substituents that correspond to each indicated property. The substituents are written as -XY, where X is the atom directly bound to the aromatic ring. These substituents activate the ring These substituents withdraw electrons towards substitution. through resonance. -CN V -COOH -CH, -OCH, O -NO2 -NH, V -CN -NHCOCH, Incorrect These substituents give ortho/para-directed substitution. -F -CH

4) Aromatic compounds are among the most abundant and versatile in nature. From a synthetic point of view, these compounds, despite their stabilities, are quite useful and can undergo reactions under special conditions and by specific mechanisms, such as the Electrophilic Aromatic Substitution (SAE) and the Nucleophilic Aromatic Substitution (SNAr). Based on this, please answer the following items: (a) What are the possible isomeric products for the following reaction? Which structure, A or B, do you expect to predominate? Justify your choice. Write down the detailed mechanism of formation of compounds A and B. What would be the bromination product of each (compounds C and D)?
