Can All Polar Molecules Form Hydrogen Bonds
The theory of whether polar protons can all form hydrogen bonds
The polar protons of the world have different properties, and they cannot all be formed by hydrogen bonds.
The polar proton, although polar, forms a hydrogen bond, which still requires specific conditions. A hydrogen bond is a weak interaction between a hydrogen atom and an atom with strong electronegativity (such as fluorine, oxygen, and nitrogen) after covalently combining with another atom with strong electronegativity.
A polar proton, if the electronegativity of the surrounding atoms does not reach a considerable degree, or the spatial resistance is too large, even if it has polarity, it is difficult to form a hydrogen bond. For example, although some halogenated hydrocarbons are polar, the electronegativity of halogen atoms is slightly inferior to that of fluorine, oxygen, and nitrogen, and the spatial structure is complex, so it is difficult to form hydrogen bonds.
Furthermore, the environment in which polar protons are located also affects. If solvents or other molecules interact strongly with them, shielding protons or changing their electron cloud distribution will also hinder the formation of hydrogen bonds.
In summary, not all polar protons can form hydrogen bonds. It must be determined comprehensively according to many factors such as their atomic electronegativity, spatial structure, and environment to know whether they can form hydrogen bonds.
