Hydrogen bond
Mandarin:
氢键 (qīng jiàn)
氢键 (qīng jiàn)
Explanation in English Language (EN):
A hydrogen bond is a special type of attractive interaction between molecules. It occurs when a hydrogen atom is bonded to a highly electronegative atom, such as oxygen, nitrogen, or fluorine. This creates 1 a dipole, with the hydrogen atom having a partial positive charge. This positively charged hydrogen can then interact with a lone pair of electrons on another electronegative atom in a neighboring molecule, forming a hydrogen bond. Hydrogen bonds are weaker than covalent bonds but stronger than van der Waals forces. They play a crucial role in determining the properties of many polymers, including their solubility, melting point, and crystallinity.

Explanation in Mandarin (ZH):
氢键是分子之间一种特殊的吸引力相互作用。当氢原子与高电负性原子（如氧、氮或氟）键合时，就会发生这种情况。这会产生一个偶极子，其中氢原子带有部分正电荷。然后，这个带正电的氢可以与相邻分子中另一个电负性原子上的孤对电子相互作用，形成氢键。氢键比共价键弱，但比范德华力强。它们在决定许多聚合物的性质（包括它们的溶解度、熔点和结晶度）方面起着至关重要的作用。
