一、案例背景本节课是安排在苯及其同系物、乙醇后的一节内容,已初步掌握了官能团对有机物主要性质的决定性作用。让学生通过多种方法去学习和探究。通过实验探究学习苯酚的性质。让学生学会全面地看待问题,能更深层次地掌握知识。二、案例主题本节课是首先介绍了自然界中的酚类化合物,然后介绍最简单的酚类化合物——苯酚,由醇类作对比让学生分析苯酚分子结构特点,通过实验来学习苯酚的性质,通过比较苯和苯酚以及醇和苯酚的性质来学习羟基和苯环之间的相互影响。要求学生通过本次探究实验,掌握苯酚的主要化学性质,掌握一定的实验技能技巧。同时通过分析苯酚的结构,联系有关有机化合物的知 First, the case background This lesson is arranged in benzene and its homologues, a section after the content of ethanol, has initially mastered the functional groups on the main nature of the decisive role of organic matter. Have students learn and explore in a variety of ways. Exploring the nature of phenol by experiment. Allow students to learn a comprehensive view of the problem, can grasp the knowledge of a deeper level. Second, the case theme This lesson is the first to introduce the phenolic compounds in nature, and then introduce the simplest phenolic compounds - phenol, compared to alcohols for students to analyze the structural characteristics of phenol molecules, through the experiment to learn the nature of phenol , By studying the nature of benzene and phenol and alcohol and phenol to learn the interaction between hydroxyl and benzene rings. Require students to explore through this experiment, master the main chemical properties of phenol, master a certain amount of experimental skills. At the same time through the analysis of the structure of phenol, contact with the knowledge of organic compounds
