SN2 reactions are highly useful in organic synthesis because they enable use to convert one functional group into another —— functional group transformation (functional group interconversion)

根据顺序功能图,用辅助继电器M代表 各步,使用有记忆(或保持)功能的电 路(起保停电路)来控制代表各步的辅 助继电器

The C—X bond of alkyl halides is polarized. The carbon atom bears a partial positive charge, The halogen atom a partial negative charge

21.11 Aryl Halide and Nucleophilic Aromatic Substitution 21.12 Spectroscopic Analysis of Phenols and Aryl Halides

Quinones are an interesting and valuable class of compounds because of their oxidation-reduction, or redox, properties. The redox properties of quinones are important to the functioning of living cells, where compounds called ubiquinones(泛醌) act as biochemical oxidizing agents to mediate the electro-transfer processes involved in energy production

Phenols are like alcohols in being able to form strong intermolecular hydrogen bonds. Phenols have higher boiling points than hydrocarbons of the same molecular weight. A modest solubility in water
