1.Glycine, alanine, valine, leucine are all nonpolar assets and this is how you drop them in an exam.

酸，丙酸，缬酸，亮酸全都极性的，这就你如何征服考试的秘诀啦！

2.But water does not dissolve non-ionic, nonpolar substances.

但水不溶解离子、极性物质。机翻

3.So the methane molecule becomes nonpolar as a result of that.

所以甲烷分子因此变得极性。机翻

4.So this one's nonpolar, and, of course, this one's nonpolar.

所以这极性的，当然，这极性的。机翻

5.Therefore, these simple hydrocarbons are pretty nonpolar and their electrons are distributed evenly over the molecule, which is why, you know, oil and water don't mix.

因此，这些简单的碳氢化合物极性的，它们的电子均匀分布在分子上，这就油和水不混合的原因。机翻

6.In this video, we're going to see how we figure out whether molecules are polar or nonpolar and also how to apply that polarity to what we call intermolecular forces.

在本视频中，我们将了解如何确定分子极性的还极性的，以及如何将极性应用于我们所谓的分子间作用力。机翻
