中文简介:
"所以, 去年, 我们讨论了二次粘合, 我们研究了各种形式的二次粘合。这里有卡通片, 偶极子相互作用, 偶极子诱导, 偶极子在溶液中, 一点点的分流, 诱导偶极子, 诱导偶极子, 这是伦敦分散力量, 或范德华键, 还有氢债券。帮助我们回答了一个问题, 聚合的状态是什么?我们想知道聚合状态的原因是, 这是固态化学。我们想知道什么时候东西是 sol".///所以, 这有助于我们得出这个结论。然后, 我们来到了这样的地步: 我们意识到, 四分之三的周期表既没有被离子粘合, 共价键, 或范德华粘合作为一种主要形式的粘合覆盖.....。
课程简介: //"So, last day, we talked about secondary bonding, and we looked at various forms of secondary bonding. Here's the cartoons, dipole-dipole interactions, dipole induced, dipole in solutions, a little bit of a diversion, induced dipole, induced dipole, which was the London dispersion forces, or van der Waals bonds, and also hydrogen bonding.// //And, all of these helped us answer the question, what's the state of aggregation? The reason we want to know the state of aggregation is that this is solid-state chemistry. And we want to know when something is a solid.// //So, this helps us get to that conclusion. And, then we came to the point where we realized that three quarters of the periodic table wasn't covered by either ionic bonding, covalent bonding, or van der Waals bonding as a primary form of bonding..."
