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。
