adj.非（无）极性的

Carbon dioxide (CO2) is a nonpolar molecule due to its symmetrical structure.
二氧化碳（CO2）由于其对称结构是非极性的。
Water (H2O), on the other hand, is polar because of the difference in electronegativity between hydrogen and oxygen atoms.
相比之下，水（H2O）是极性的，因为氢和氧原子的电负性不同。
Methane (CH4) is a nonpolar compound, with all four C-H bonds having equal sharing of electrons.
甲烷（CH4）是一个非极性分子，四个C-H键电子共享均等。
Ethane (C2H6) is nonpolar as the carbon-carbon bond and carbon-hydrogen bonds are symmetrical.
乙烷（C2H6）是非极性的，因为碳-碳键和碳-氢键都是对称的。
Bromine (Br2) exists as a nonpolar diatomic molecule due to its identical electron distribution.
溴（Br2）以非极性双原子分子形式存在，因为其电子分布相同。
In an oil-water mixture, the immiscible liquids do not interact due to their nonpolar nature.
在油水混合物中，由于它们的非极性，不相溶液体不会相互作用。
The surface tension of nonpolar solvents like hexane is lower than polar solvents like water.
非极性溶剂如己烷的表面张力低于极性溶剂如水。
Nonpolar solvents dissolve nonpolar substances better, like fats and oils.
非极性溶剂能更好地溶解非极性物质，如脂肪和油。
The Van der Waals forces between nonpolar molecules are weaker than those between polar molecules.
非极性分子之间的范德华力比极性分子间的弱。
Iodine crystals form a nonpolar lattice structure, which is why they do not conduct electricity.
碘晶体形成非极性晶格结构，这就是为什么它们不能导电。
