So if you picture, for example, b h 3, it's going to look like this.
如何使键劲量相互远离,我们会有平面三角形的情形,如果你想象。
All right, so if we think about b h bond here, again, it's the sigma bond, and we're going to say it's a boron 2 s p 2 hybrid orbital interacting with a hydrogen 1 s orbital.
这可以告诉我们,为什么它倾向于周围只有6个电子,好了,考虑一下这里的BH键,同样的,它是sigma键,我们说。
