Unformatted text preview: It is not necessary to draw both resonance structures for an aromatic ring, however. Note that this reaction occurs under acidic conditions, so any charged intermediates should be cationic!!! You may assume that hydronium (H 3 O + ) is present under the given reaction conditions – you do not need to show how H 3 O + is formed. H 2 O H 2 SO 4 (cat.) H O H H H H O H H H H H O H H O H H...
