有机分子结构中由于碳原子形成不同价键,造成空间构型存在差异,成为高考命题的采分点之一,掌握课本中典型分子的空间构型和判断技巧会使问题迎刃而解.一、课本中典型分子的空间构型1.典型分子的空间构型甲烷:正四面体结构,4个C-H键不在同一平面上,凡是碳原子与4个原子形成4个共价键时,空间结构都是正四面体,键角均为 Organic molecules in the structure due to the formation of different valence bond carbon atoms, resulting in differences in the spatial configuration, a college entrance examination scores one of the points to master the typical textbook textbook spatial configuration and skills will make the problem solved. Spatial Configuration of a Typical Molecule 1. The Spatial Configuration of a Typical Molecule Methane: a tetrahedron structure with four CH bonds not on the same plane. Where four carbon atoms and four atoms form four covalent bonds, the spatial structure is positive. Body, key angle are
