有机实验和无机实验是构成化学实验的两大部分,全国理综考试对实验的考查,多集中于无机实验,而对大型有机实验题考得很少。2001年上海高考试题27题涉及了天然气合成氨的综合问题,2002年上海高考试题26题考查乙炔和溴水的反应机理问题,2005年上海高考试题26题考查了溴苯的制取装置、28题则考查了对废旧塑料进行加工回收的实验。今年上海、江苏和广东都考查了有机实验,有机实验可能是今后全国理综高考实验的命题方向,下面介绍一组以教材内容为依托,自然延伸的有机实验。
Organic and inorganic experiments constitute two major parts of chemical experiments. Examinations of experiments in the National Liberal Arts Examination focused on inorganic experiments, but few on large-scale organic experiments. The 27 questions of the 2001 Shanghai Exam Question related to the synthesis of ammonia from the natural gas issue. The 2002 Shanghai Exam Questions 26 questions examined the reaction mechanism of acetylene and bromine water. In 2005, the Shanghai Exam Question 26 examined the preparation of bromobenzene, 28 questions. Then we examined the experiment of processing and recycling waste plastics. This year, Shanghai, Jiangsu, and Guangdong have all examined organic experiments. Organic experiments may be the propositional direction of future national college entrance examinations. The following describes a set of organic experiments that rely on the content of textbooks to extend naturally.
