那么让我们看看怎样,推导这些反应，现在让我问一下,这里有谁学过5。111？谁学过5。112？

So I just have to see, oh, here's a D, let me keep looking, D here's an A, keep looking here's a V, here's an I, here's a D and yet, and this is one tidbit we introduced a week or so ago, how do I now know if I'm just given the address of the start of the string where the end is?

Often a good thing to start with is to put the lowest ionization energy atom in the middle, and if you don't have charge separation then go with that structure, but if you do find you have a lot of separation, such as the case in negative 2, positive 2, and minus 1, then you want to say wait a second, this is really bad in terms of formal charge, let me go ahead and see what other options I have here.

通常一开始把电离能最低的原子,放在中心位置就很好了，如果你发现电荷没有分开,那么这个结构就没问题了，但是如果你发现有很多分开的电荷，比如这种情况，有负二，正二和负一，那么你会想要说等一下，从形式电荷来看这很不好，让我去看看其它可能的选择。
