补充资料:取向力

相同元素两原子间形成的共价键为非极性键,不同元素原子间形成的共价键为极性键。极性键中,共用的电子对偏向电负性大的原子,因此电负性大的原子带部分负电荷(δ-),而电负性小的原子则带部分正电荷(δ+)。电负性差异越大,键的极性将越大。多原子分子的极性除了与各键的极性有关外,还决定于分子空间构型。若分子对称性很高,使各键极性相互抵消,则分子将无极性。如c—o是极性键,但co2是直线型对称分子,两键极性相消是非极性分子。h2o中h—o是极性键,它是v型结构,键的极性不能抵消,因而h2o分子有极性,是极性分子。

极性分子可视作偶极子,其极性用偶极矩μ=qd来衡量,即正或负电荷电量(q)与电荷中心间距d的乘积。μ一般在10-30c·m数量级。μ=0的分子为非极性分子,μ越大,分子极性越大。测定分子偶极矩是确定分子结构的一种实验方法。德拜(p.j.w debye,荷)因创立此方法而荣获1936年诺贝尔化学奖。

极性分子相互靠近时,因分子的固有偶极之间同极相斥异极相吸,使分子在空间按一定取向排列,使体系处于更稳定状态。这种固有的偶极间的作用力为取向力,其实质是静电力。
