hydrogen bond 就是氢键了,就是H由于显正电,形成质子而容易被其他外层电子比较多的原子吸引而产生的键,像O 阿,S 阿,N 之类的. dipole-dipole就是偶极与偶极之间的作用,主要就是极性分子中正负电荷中心不重合而产生了极性,这样偶极之间就有了作用力. London dispersion force:非极性分子间仍存在吸引力.这起因于分...
2. hydrogen bonding氢键 正常沸点随着分子量的增加而增加,就像CH4到SeH4这条线,但是我们会发现NH3要特别高,比原来预计的要高,因为氢键的存在。注意:所有和水有关的特性都与水的氢键有关。 3. London dispersion force: induced dipole-induced dipole force between non-polar molecules London dispersion force随着...

London Dispersion Forces Hydrogen Bonding In general, the strongest type of intermolecular force (ex: 13 - 40 kJ/mol energy required to break hydrogen bond, and 1 - 25 kJ/mol energy required to break dipole- dipole interactions), it occurs for species that have the atoms of Nitrogen, ...

SAT2化学中的dipole-dipole和dispersion是啥意思?(都是两种键,具体是.)相关知识点: 试题来源: 解析 你确定是两种键吗? 我觉得第一个是两种分子之间的相互作用力,也就是dipole-dipole-force,第二个是白光过三棱镜时的散射. 分析总结。 我觉得第一个是两种分子之间的相互作用力也就是dipoledipoleforce第二个是白光...

Dipole-Dipole Interactions - Forces of attraction that draw molecules together are called intermolecular forces. The three main intermolecular forces are London dispersion forces, dipole-dipole interactions and hydrogen bonding. Dipole-dipole interaction
dipole-dipole interactions 是偶极-偶极相互作用力 它比分子间的范德华引力小,可以改变高分子材料的相溶性。dispersion force是色散力 非极性分子间也有相互作用,例如室温下苯是液体,碘、萘是固体。在低温下CI2、N2、O2甚至稀有气体也能液化。此外,对于极性分子来说,由前两种力算出的分子间作用能也...
