So if you think about any one of these carbon-carbon bonds, what type of a bond would you expect that to be?

如果你们考虑任何一个碳碳键，它是什么类型的？

So in terms of thinking about ethane, we actually have two bond types that we're going to be describing just in terms of the carbon-carbon bond and then the carbon h bonds.

对于乙烷，我们有两种键,我们继续讨论一下,碳碳键,和碳氢键。

As we see a little bit later, I could talk about the carbon-hydrogen bond in methane where there is a plurality of bonds. In this case, there is only the one bond but I just want to get the formulas.

因为我们后来看到一点点，我能讨论甲烷中的碳氢共价键,那有许多共价键，这种情况下，这只有一条共价键,但我想得到氟。

And the last bond that we have here is a carbon-carbon bond, and this is our last p orbitals that are coming together.

最后一个键是碳碳键，这是最后一个组合的p轨道。

So let's take a look at what actually happens if we're talking about a carbon-carbon double bond, we're going to have a double bond.

让我们来看一看碳碳双键的情况,例如在乙烷里，我们有个双键。

Now I want to ask, what's the nature of the carbon-hydrogen bond?

现在我想问问，碳氢键的本质是什么？

So in terms of the carbon hydrogen bond, it's a sigma bond, - because we define it -- any time we are bonding to an atom, we have to keep redefining our bond axis to whatever two atoms we're talking about.

对于碳氢键，它是sigma键，因为我们定义它-,任何时候我们有原子成键，我们要重新定义键轴方向,为我们所讨论的两个原子方向。
