与无机化学实验相比,有机化学实验的特点是反应速度慢,通常要加热或加催化剂,副反应也较多。实验的反应物、生成物大都易挥发、易燃烧,有的还有毒,容易污染环境。根据多年的教学实践,笔者认为要提高有机化学实验课的教学质量必须抓好以下几点:1.注意培养学生的观察能力,认清有机反应的复杂性观察现象是实验成功的一个重要环节。针对有机化学实验的特点,要培养学生全面、细致的观察整个实验。如:在苯与氯气的加成反应
Compared with inorganic chemistry experiments, organic chemistry experiment is characterized by slow reaction, usually heating or catalyst, side effects are more. Experimental reactants, most of the products are volatile, easy to burn, and some are toxic, easy to pollute the environment. According to years of teaching practice, I believe that to improve teaching quality of organic chemistry experiment class must pay attention to the following points: 1. Pay attention to cultivate students’ observation ability, recognize the complexity of organic reaction observed phenomenon is an important part of the experiment. According to the characteristics of organic chemistry experiment, it is necessary to train students to observe the whole experiment comprehensively and meticulously. Such as: benzene and chlorine addition reaction
