So let's take the case of acetylene where we have two carbon atoms that are going to be triple bonded to each other, each are bonded to a carbon and then to one hydrogen.

让我们来看一看乙炔的例子,我们有两个碳原子,成三键，每个碳和一个碳一个氢相连。

As we see a little bit later, I could talk about the carbon-hydrogen bond in methane where there is a plurality of bonds. In this case, there is only the one bond but I just want to get the formulas.

因为我们后来看到一点点，我能讨论甲烷中的碳氢共价键,那有许多共价键，这种情况下，这只有一条共价键,但我想得到氟。

So in one case, we could actually put carbon in the middle, in one place, we could put sulfur in the middle, and in one case we could put nitrogen.

那么有一种情况是，我们把碳放在中间，还有一种情况是，把硫放在中间，另外一种情况是把氮放在中间。

If we look at our last structure here where we have nitrogen the middle, we can also figure out all those formal charges, and in this case we have plus 1 on the nitrogen, we have minus 2 on the carbon, and then we end up with a 0 on the sulfur there.

如果我们来看看最后一个结构,在中间的原子是氮，我们同样可以计算出所有的形式电荷，而在这种情况下，氮为正一，碳为负二，而最后硫为零。

However, we're going to see that that's not the case for hydrogen and carbon.

但是我们发现,将其应用于C和H中。

So let's take a look at another case where we have s p 2 hybridization, we can actually also have it happen in carbon.

它是B2sp2杂化轨道,和H1s轨道的相互作用，让我们看看另外一个。
