Sigma that is one PI orbital. There is one sigma, one PI and there is a second PI, and that is how we are getting the triple bond.
那是一个pi轨道，有一个，一个pi，还有第二个pi轨道，这就是我们如何得到三线态的。
Halogen atom could activate the triple bond and as the directing group, the triple bond occurs the electrophilic addition reaction.
卤原子作为保护基，代替末端炔发生碳-氢官能团化反应。
So, if we talked about a nitrogen-nitrogen single versus double versus triple bond, the triple bond will be the shortest and it will be the strongest.
因此，如果我们讨论的是氮与氮之间的单键，双键与三键，那么三键应该是其中最短的一个，同时也是最强的一个。
And something that we'll see later on is that triple bonds, for example, are going to be stronger than a corresponding double bond or a corresponding single bond.
而我们以后还会看到三键，举例来说，应该更强，相较于相应的双键，或者相应的单键来说。
This is very easy molecule because we know exactly where to put them without even having to think, we only have one option, and we'll make a triple bond between the carbon and the nitrogen.
这个分子非常简单，因为我们知道应该把它们放在哪里，甚至不用去想，我们只有一个选择，我们将在碳与氮之间形成一个三键。
So, for example, down here I wrote that it was n 2 and that it was h 2, but when I re-wrote the molecules up here, you saw that it's an h h single bond where it's a nitrogen-nitrogen triple bond.
比如，在这下面我写的是氮分子2,而这个是氢分子，但我在上面把这些分子的形式改写了，大家可以看到,这是一个氢与氢之间的单键，含一个氮与氮之间的三键。
