So, if we think about what bonds are in this molecule, sp2 we actually have six of these sigma carbon s p 2, carbon s p 2 bonds.
如果我们考虑这个分子里都有什么键,我们有六个sigma碳,碳sp2键。
So if you picture this as our s p 2 carbon atom where we have three hybrid orbitals, and then one p y orbital coming right out at us.
如果你把这想象成sp2碳原子,这里有3个杂化轨道,然后一个py轨道朝向我们。
So it's along the bond axis and it's between a carbon s p 2 hybrid, and then the hydrogen is just a 1 s orbital that we're combining here.
所以它是沿着键轴方向的,而且这里是一个碳sp2杂化轨道,和一个氢的1s轨道的结合,在这里我们可以合并他们。
Again, the name is very straightforward, it comes from 1 s and 2 p orbital, so it will be s p 2.
所以,如果我们杂化这三个轨道,我们最后会得到的是sp2杂化轨道,同样,这个名字是很直接的。
So in s p 2 hybridization, instead of combining all four, we're just combining two of the p orbitals with the s orbital.
这样就能得到sp2杂化,在sp2杂化中,不是四个轨道结合。
And again, you might be thinking well, why didn't we actually hybridize this 2 p y orbital.
它来自1s和2p轨道,所以它是sp2,同样。
sigma So we'll call this sigma, and it's between two s p 2 hybrid carbon atoms.
我们可以叫它,它在两个sp2杂化碳原子之间。
We also have carbon s p 2 hydrogen 1 s bonds.
我们还有碳sp2氢1s键。
So it's stigma carbon s p 2, carbon s p 2.
所以它是sigma碳sp2碳sp2。
So again, we can think of an example here.
和三个杂化的sp2轨道。
