So, if we think about the second case here where we have c n minus, now we're talking about a molecule with a net charge of negative 1.
那么,如果我们考虑的是第二个例子,也就是氰离子,那么现在我们讨论的是一个净电荷量为负一的分子。
So, let's try another example here, and let's try a case now where instead of dealing with a neutral molecule we have an ion, so we have c n minus.
那么,让我们来试一下另外一个例子,这次不是一个中性原子,而是一个离子,氰离子。

This backlash N, it's also a recurring theme and not just in C but in PHP, JavaScript, other languages as well.
还有反斜杠n,不仅C语言里有,在其他语言像PHP,JavaScript等都会碰到。

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 if you're trying to make a more complicated organic molecule carbon-carbon bonds are one of the most difficult things to make in organic chemistry, and it turns out that c n minus is a very reactive molecule, so it's a good way, even though we'll go over some drawbacks in a second, it is a good way to make carbon-carbon bonds.
如果你要合成一个更复杂的有机分子,碳碳键是有机化学中,最难制造的键之一,而实际上氰离子是一种具有很高活性的分子,用它是一个好办法,尽管我们一会儿将看到它的一些缺点,但它的确是一个制造碳碳键的好方法。
C-A-N-S-U An S in the side so Cansu, that was spelled C-A-N-S-U.
有一个S喔。
