  • I have the skeletal structure written up there, I've written it twice and you'll see why in a minute.

    我已经把它的骨架结构画在上面了,我画了两遍,等会你就会知道为什么。

  • So, if we use those two tips to try to figure out a structure, a skeletal structure, we would get this structure here if we write out the full Lewis structure.

    那么,如果我们用这两个小窍门来,尝试写出它的结构,骨架结构,我们将会得到这样的结构,如果我们把完整的路易斯结构画出来的话。

  • So in terms of the first step of skeletal structure, this is actually going to be easier because we don't have a central atom, we just have carbon and nitrogen here.

    对于第一步画出骨架,其实比刚才更容易,因为我们没有一个中心原子,我们这里只有碳和氮两个原子。

  • It's easy to write the skeletal structure, because it's all oxygen, we don't have to worry about what's going to go in the middle.

    画它的骨架结构很容易,因为它们都是氧原子,我们不需要担心哪个原子在中间的问题。
