You might have thought before we started talking about molecular orbital theory that non-bonding was the opposite of bonding, it's not, anti-bonding is the opposite of bonding, and anti-bonding is not non-bonding.

你也许在我们讨论分子轨道之前,就想过非成键时成键的反面，它不是，反键才是成键的反面，反键不是非成键。

And, we have two non-bonding domains.

我们有了两个非键区域。

2 3 So, that means we've got one, two, three, four nonpolar bonds in here.

我们有，4个非极性的键。
