本章教学的基本任务:通过本章有机物名称的来源和有机化合物正确的意义的讲述,使学生了解唯物的合成理论战胜了唯心的“生命力”理论后,有机化学才得到了突飞猛进的发展;从而理解唯物观点在科学工作上的重要意义。为了复习以前学过的克分子体积和分子量的求法,我们建议增加两堂复习课,使学生系统的了解化学计算发展的阶段,再讲述导出实验式和分子式的方法,才能使学生彻底了解实验式与分子式的区别和测定它们所根据的原
The basic task of teaching in this chapter: through the sources of organic names in this chapter and the narration of the correct meaning of organic compounds, to enable students to understand that the synthetic theory of material material has overcome the ideal “vitality” theory and organic chemistry has been developed by leaps and bounds; thus understanding materialism The point of view is of great importance in scientific work. In order to review the previously learned molecular volume and molecular weight, we propose to add two review classes to enable students to systematically understand the stage of stoichiometric development and then to derive experimental and molecular formulas in order to enable students to fully understand the experimental Differentiate from the formulas and determine the bases on which they are based
