对于一些特殊的联苯衍生物及其类似化合物,通过构型和构象,同样可以利用螺旋理论推断其旋光方向;通过旋光方向和大小,也可以推断其绝对构型。2) chair conformation and boat conformation 椅型构象和船型构象3) chair conformation 椅型构象4) boat confomation 船型构象5) staggered confor-mation and eclipsed confor...
a键电子偏向一方的共价键称为极性键,由一方提供成键电子的键称为配位键。通过这些类型的键把原子按一定的空间排列结合成分子,形成分子的构型和构象。 A bonding electrons deviation side covalent bond is called the polar bond, provides the bonding electrons by a side the key to be called the coordination...
通过这些类型的键把原子按一定的空间排列结合成分子,形成分子的构型和构象。 Locates the key is called the localization key between 2 atoms.The multi-central key which altogether has the electron to form is called by many atoms to the territory key.In addition also has the transitional form key: ...
