{"knowledge_schema": {"broad_category": "Chemistry \u2192 Organic Chemistry \u2192 Electrophilic Aromatic Substitution", "refinement": "This problem involves understanding the reactivity of aromatic compounds in electrophilic aromatic substitution reactions, specifically the bromination process.", "specific_scope": "The focus is on determining which aromatic compound will preferentially yield the ortho-bromo derivative when reacted with bromine, considering the effects of substituents on the aromatic ring.", "goal": "Identify the compound that will produce the highest yield of the ortho-bromo derivative based on the influence of substituents on the aromatic system."}, "summary": "This problem is centered on the concept of electrophilic aromatic substitution in organic chemistry, specifically the bromination of aromatic compounds. The task is to evaluate how different substituents on the benzene ring affect the yield of ortho-bromo derivatives when reacted with bromine. The compound C6H5-CH3 (toluene) is identified as having the highest yield due to the methyl group being an ortho/para-directing activator, enhancing the reactivity of the ring towards bromination at the ortho position."}
