"On whether carbon dioxide can form hydrogen bonds"
Everything in the world follows the rules of physics. Carbon dioxide has a well-established molecular structure, and it is an interesting scientific mystery to investigate whether hydrogen bonds can be formed.
The formation of hydrogen bonds requires hydrogen atoms to be closely connected to atoms with strong electronegativity and small radius (such as fluorine, oxygen, and nitrogen) before hydrogen bonds can be formed. Carbon dioxide molecules, whose chemical formula is $CO_2 $, have carbon atoms in the center, and are connected to oxygen atoms by double bonds on both sides. There is no situation where hydrogen atoms are directly bound to strong electronegative atoms.
From the perspective of molecular structure, the structure of carbon dioxide is linear, $O = C = O $, and the electron cloud is relatively symmetrical on both sides of the molecule. If hydrogen atoms want to participate in the formation of hydrogen bonds, they need a suitable electron cloud environment and spatial location, but the structure of carbon dioxide is difficult to provide this condition.
Then consider the principles of physical chemistry. The formation of hydrogen bonds is related to the change of intermolecular forces, which affects the melting point, solubility and many other properties of substances. If carbon dioxide can form hydrogen bonds, its related properties should be very different from existing knowledge. However, looking at the experimental data and actual observations, the properties of carbon dioxide are contrary to the theoretical expectations of hydrogen bond formation.
Therefore, according to the existing scientific knowledge and theoretical analysis, it is difficult for carbon dioxide to form hydrogen bonds. Although this conclusion is based on current knowledge, although scientific development is endless, or new discoveries in the future can be re-examined, at present, there is no condition for carbon dioxide to form hydrogen bonds.
