中学有机化学是由烃、烃的衍生物、糖类和蛋白质以及合成有机高分子化合物等四章组成,在这四章中烃是基础,烃的衍生物是重点,从分子中含有两个官能团的双重性能以及加聚反应和缩聚反应的实质来看,后两章是前两章知识的发展和应用,所以着力讲授好前两章,是讲好整个有机化学的基础.从前两章来看,烃又是基础,因为在烃一章教学中,发展了物质结构理论,提出了碳原子轨道杂化,σ键、π键的概念,建立起分子立体结构的初步形象,揭示了物质结构与性质的内在联系.同时提出了同系物,同分异物体,结构式,有机物的命名等学习有机化学必备的基础知识.正确认识和估价烃在整个有机化学教学中的作用和地位,对教好这章课文的意义是不可忽视的,下面谈谈我对烃一章教学的两点看法:
Secondary chemistry is composed of hydrocarbons, hydrocarbon derivatives, carbohydrates and proteins and synthetic organic polymer compounds, four chapters, in these four hydrocarbons is the basis of hydrocarbon derivatives is the focus, from the molecule contains two functional groups Of the dual performance and polyaddition reaction and polycondensation reaction in essence, the latter two chapters is the development and application of the first two chapters of knowledge, so focus on teaching the first two chapters, is to talk about the whole organic chemistry foundation. , Hydrocarbon is the foundation, because in hydrocarbon teaching, the theory of material structure has been developed, the concept of carbon atom orbital hybridization, σ bond and π bond has been proposed, the preliminary image of molecular stereoscopic structure has been established, and the relationship between material structure and Nature of the relationship between the same time put forward the homologue, the same object, structure, the nomenclature of organic materials and other basic knowledge necessary to learn organic chemistry.Correct understanding and evaluation of hydrocarbons in the role of organic chemistry teaching and status, to teach good The significance of this chapter text can not be ignored, the following talk about my point of view on hydrocarbon teaching two points:
