前言含氟有机化合物大多具有一般化合物所没有的特性,这是因为氟原子有如下诸多特性:在体积上氟是仅次子氢的小原子(H 和 F的范德华半径分别为1.2A~。和1.35A~。);具有强电负性,与碳的键合力比氢和氟以外的卤素原子强,此外,碳—氟键的键距(键长)短(1.32A~。),无柔性,极化率低。基于氟的上述特性,有机氟化合物与极 Introduction Most of the fluorine-containing organic compounds have properties that are not found in typical compounds because fluorine atoms have many properties as follows: fluorine is the only second-atom small atom in volume (van der Waals radii of H and F are 1.2 A ~ 1.35A ~.); With strong electronegativity, and carbon bonding force than hydrogen and fluorine halogen atoms, in addition, the carbon-fluorine bond length (bond length) is short (1.32A ~ , Low polarizability. Based on the above characteristics of fluorine, organic fluorine compounds and polar
