We can say that a nonpolar molecule you can have as a result of two different conditions.
所以你可以说非极性分子,有两种构成方式。
Nonpolar molecules result from either, it's one or the other.
一个非极性分子,不是这一种就是那一种。
Here is the question. Is methane a polar molecule or a nonpolar molecule? Let's look carefully.
问题是,甲烷是一个极性分子还是非极性分子,我们仔细看看。
We only have the one bond so the actual HF molecule is polar, it has a net dipole.
但HF中只有一根键,所以分子也是极性的而甲烷中有一个网状偶极。
Symmetric disposition of polar bonds still results in a nonpolar molecule.
空间对称的极性键分布,还是会导致整个分子为非极性分子。
We know that it's non-polar.
我们都知道他是非极性分子。
If we can do that, we'll end up with a symmetric nonpolar molecule.
如果我们能这样做,我们就能得到那些对称非极性的分子。
And yet, the molecule is symmetric and nonpolar.
所以这个分子是对称非极性的。
This is homonuclear and so these are nonpolar.
这是同核分子所以是非极性的。
All of these multiatomic moieties are nonpolar.
这些分子由多原子组成,但都是非极性的。
What makes something polar versus nonpolar?
是什么让一个分子呈极性或者非极性?
This bond is polar, but again, as I alluded to earlier, because the carbon is centered in the tetrahedron, because of the sp3 hybridization, the molecule itself is symmetric and nonpolar.
这个键是非极性的,但是,我们断言过早,因为C是中心原子,由于sp3杂化,这个分子本身是非极性的且对称的。
