范德华力分子式：CAS号：性质：又称范德瓦尔斯力。最早提出并成为分子间作用力主要内容的存在于中性分子或原子之间的一种弱的电性吸引力。包括：(1)极性分子的永久偶极间的静电力(又称Keeson force)；(2)一个极性分子使另一个分子极化产生诱导偶极并相互吸引的诱导力(又称Debye force)；(3)分子中电子运动产生瞬时偶极，使邻近分子瞬时极化，反过来又增强原来分子的瞬时偶极，这种相互耦合产生净的吸引作用力称色散力，或伦敦力(London force)。它们相应的作用能与分子质心间距离厂的六次方成反比。对于不同的分子，以上三种力所占比例不同，通常色散力占主导。范德华力大约只有(10～20kJ/mol)，比一般化学键键能小得多，没有方向性和饱和性。它们影响物质性质。中性分子和惰性气体原子就是靠范德华力凝聚成液体或固体。在气、固表面，由于范德华力可发生范德华吸附。
