二、分析“第三章烃”烃是作为有机化合物的母核来介绍的,我们必须通过烃的通性来阐明这个意义。首先要阐明烷的化学性质极不活泼和相同类型结构的化合物具有相同性质的化学性质。这样为同系列的概念先打下基础。同时,必须清楚地说明饱和性和不饱和性;脂肪性和芳香性的特性以及它和结构的相互关系。这些都是最基本的概念必需使学生有明确的认识。我们也可以适当的介绍有机化学命名原则。
Second, the analysis of “Chapter III hydrocarbons” hydrocarbons are introduced as the mother nucleus of organic compounds, we must clarify the significance of the hydrocarbon through the nature of. First of all, it is necessary to clarify the chemical nature of the alkane is very inactive and the same type of chemical structure of the compound has the same nature. This laid the groundwork for the concept of the same series. At the same time, the saturation and unsaturation must be clearly stated; the properties of the fatty and aromatic as well as its interplay with the structure. These are the most basic concepts that must be made clear to students. We can also properly introduce the principles of organic chemistry nomenclature.
