This is the structure of Lunesta, and you see the c l in it as well.

这是鲁尼斯塔的结构图，大家可以看到这里也有氯。

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。

Well in C and many similar languages, you have to implement that same bracing structure with your keyboard using an open curly brace and a closed curly brace, so a tiny little detail.

在C语言和一些类似的编程语言中,你也必须搭建同样的架构,同样也得注意前大括号啊,后大括号啊等等这些细节问题。

So, in terms of finishing our Lewis structure, we're actually not done yet here, even though we have full octets, and we've used up all of our valence electrons, and the reason is because it's c n minus, so we need to make sure that that's reflected in our Lewis structure, so let's put it in brackets here, and put a minus 1.

那么，根据我们的路易斯结构的完成情况，我们实际上还没有全部完成，尽管我们有了填满的“八隅体“,而且用完了所有的价电子，原因就是因为这是一个负离子，我们需要确保我们的路易斯结构能反映出这一点，所以让我们给它加个括号，再加个负一。

So, let's just arbitrarily put it between these two in this case here, but actually there's no reason we couldn't also put it between oxygen b and c, so I'm going to draw another structure where we have it here.

那么，让我们任意地将它们放在这两个之间，但实际上我们没有理由,不能把它们放在氧原子，B，与，C，之间，因此我将把另外一个结构画在这里。

you can look on your notes, C it also says structure a, b, and c on your notes, so you didn't need to have just memorized that slide.

大家可以看你们的讲义，讲义上也把它们叫做结构，A，B，和，因此大家不需要去记那张幻灯片。
