So, let's look at this in a more simple structure here where we have the two possible forms of benzene, and the reality is is that it's going to be some combination of the two.

让我们从一个更简单的结构,来看看这两种可能的苯环构型，实际情况,是这两个的组合。

But, of course, what you saw in recitation, and hopefully, what you can now think very quickly by looking at this, is that this is not the only configuration of pi bonds that we could have in benzene.

当然，你们在习题课看到过，你们通过看这个可以很快的想到，这不是苯环里,唯一的π键构型。

All right, so let's think of a more complicated example of having a double bond, and maybe a more interesting example, and this is talking about benzene.

好了，让我们来看关于双键的,一个更复杂的例子，也许是更有趣的例子，我们要讨论苯环。
