中心原子的杂化类型、分子或离子空间构型的判断在新课标高考卷的选做题中经常涉及,学生对于此题经常做出错误的判断,笔者根据自己的教学积累,对以上问题的解决提出一些自己的想法。通过对历年高考卷的分析,我们可以发现在近年高考中,分子或离子的空间结构主要是考查两个内容,即:分子或离子的空间构型、中心原子的杂化类型。而分子或离子的 The central atom of the hybrid type, the molecular or ionic spatial configuration of judgments in the New Curriculum Entrance Examination papers are often involved in the essay questions, students often make the wrong judgment, the author according to their own teaching, the above problems The solution put forward some own ideas. Through the analysis of the college entrance examination papers over the years, we can find that in recent years the entrance examination, the molecular structure of ions or ions mainly examine the two elements, namely: the spatial configuration of molecules or ions, the central atom hybrid type. And molecular or ionic
