Can CO2 Form Hydrogen Bonds
Whether carbon dioxide can form a hydrogen bond
The nature of all things depends, and the formation of hydrogen bonds also depends on its rules. If you want to discuss whether carbon dioxide can form a hydrogen bond, you need to study the rationale in detail.
Hydrogen bonding is a weak interaction between a hydrogen atom and an atom with a large electronegativity and a small radius (such as fluorine, oxygen, nitrogen, etc.) after covalent bonding with another atom with a large electronegativity. Its formation also requires that the hydrogen atom is in a specific environment and the atom it interacts with has strong electronegativity.
For carbon dioxide, its molecular structure is\ (O = C = O\). Carbon is centered, and oxygen is separated on both sides. Although oxygen is highly electronegative, in carbon dioxide molecules, the electron cloud distribution of carbon-oxygen double bonds is relatively concentrated between carbon and oxygen, and there are no active hydrogen atoms. The first condition for the formation of hydrogen bonds is to have hydrogen atoms connected to electronegative atoms. Carbon dioxide does not have this hydrogen atom. From the perspective of its molecular structure, it is difficult to meet the basic elements for the formation of hydrogen bonds.
Furthermore, in the view of common substances that form hydrogen bonds, such as water, hydrogen is connected to oxygen, and hydrogen is positive and can form hydrogen bonds with the oxygen of another water molecule. The same is true for ammonia, where hydrogen is connected to nitrogen and can form hydrogen bonds. In contrast, carbon dioxide has no such hydrogen atomic structure that can participate in the formation of hydrogen bonds, so it is difficult to form hydrogen bonds.
In summary, carbon dioxide lacks the necessary atomic conditions for the formation of hydrogen bonds due to its molecular structure characteristics, so it cannot form hydrogen bonds.
