So in addition to having these two carbon bonds, we actually also have four carbon hydrogen bonds in addition to our carbon-carbon bonds.

在这碳碳之间的键以外，我们还有四个碳氢键,除了我们的碳碳键外。

So why don't you tell me what the valence bond description would be of these carbon hydrogen bonds?

你们来告诉我,碳氢键的价,电子是怎样的？

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。

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。

Yup, we also have six of these, because we have six carbon hydrogen bonds.

嗯，6个，因为我们有6个碳氢键。

Our second bond is going to be between the carbon and the hydrogen atoms.

第二种键是,碳氢之间的键。

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？

Let's look at this carbon-hydrogen bond.

我们来看看这跟碳氢键。

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。
