如果我们考虑引入最后两个碳原子，你会看到的是对于每个碳原子，其中的两个杂化轨道，和另外的碳原子成键。

If we think about bringing in those last two carbons, what you can see is that for every carbon, two of its hybrid orbitals are being used to bond to other carbons.

在这之前我们要引入价电子成键理论，和杂化轨道的概念。

And to do this we're going to introduce valence bond theory, and the idea of hybridization of orbitals.
