第13章烃的衍生物第一节溴乙烷卤代烃1．(高考课标全国卷)下列各组中的反应，属于同一反应类型的是( )A．由溴丙烷水解制丙醇；由丙烯与水反应制丙醇B．由甲苯硝化制对硝基甲苯；由甲苯氧化制苯甲酸C．由氯代环己烷消去制环己烯；由丙烯加溴制1,2二溴丙烷D．由乙酸和乙醇制乙酸乙酯；由苯甲酸乙酯水解制苯甲酸和乙醇解析：选D。
溴丙烷水解制丙醇的反应属于取代反应，丙烯与水发生加成反应生成丙醇，A错误；甲苯的硝化反应属于取代反应，甲苯反应生成苯甲酸属于氧化反应，B错误；氯代环己烷发生消去反应生成环己烯，而丙烯与溴发生加成反应制得1,2二溴丙烷，C错误；酯化反应和水解反应都属于取代反应，D正确。
2．下列化合物中，能发生消去反应生成烯烃，又能发生水解反应的是( )解析：选D。
能发生消去反应的卤代烃，在结构上必须具备两个条件：①分子中碳原子数N(C)≥2；②与—X相连的碳原子(α碳)相邻的碳原子(β碳)上要有氢原子。
这样像CH3Cl一定不能发生消去反应，能发生消去子。
A选项CH3Cl只有一个碳原子，不能消去；B、C选项中β碳上没有氢原子，也不能发生消去；D项，CH3CH2CH2Br消去反应产物为CH3—CH===CH2。
而卤代烃一般都可以发生水解反应。
3．国家有关部门对家庭装饰材料进行抽查，发现具有毒气污染的材料占68%，它们会发出300多种能引发30多种疾病的有害物质。
三氯乙烯就是其中一种，其化学式为C2HCl3。
下列对三氯乙烯的叙述正确的是( )①该物质是由碳、氢、氯三种元素组成的②该物质是由三氯乙烯分子构成的化合物③该物质中碳、氢、氯的质量之比为2∶1∶3④该物质的分子是平面分子A．①② B．①③C．①②④ D．①③④解析：选C。
从三氯乙烯的分子式C2HCl3上可以看出①②正确；该物质中碳、氢、氯的质量比为(2×12)∶1∶(3×35.5)，不等于2∶1∶3，③错误；三氯乙烯的结构式可写为，可以看作是乙烯的三个氢原子被三个氯原子代替，为平面分子。
