So it looks a lot less messy if we just draw our Lewis structure like this for h c n, where we have h bonded to c triple bonded to n, and then a lone pair on the nitrogen there.

这看起来整洁了不少,如果我们把氰化氢的路易斯结构画成这样的话，这样我们就有氢与碳之间的单键和碳与氮之间三键，然后还有一对孤对电子在氮这里。

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。

And then even lower down, we have our bonded hydrogen molecule.

然后继续降低，我们就有了通过共价键结合的氢分子。

But only after we have met three or four times and have reached an understanding with each other, only then can friendship be bonded.
