Does CO2 Have Hydrogen Bonding
On the existence of hydrogen bonds in carbon dioxide
I have heard people talk about carbon dioxide, and many people ask whether it has hydrogen bonds. To understand this, we should first study the nature of hydrogen bonds.
The hydrogen bond 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 being covalently bonded, it is formed with another atom with a large electronegativity. Although this effect is weaker than the covalent bond, it has a significant impact on the properties of many substances.
View the structure of carbon dioxide, its molecular formula is\ (CO_2\), and carbon is connected to the two oxygen atoms by double bonds, showing a linear structure. The electronegativity of carbon is\ (2.5\), and the electronegativity of oxygen is\ (3.5\). Although the electronegativity of oxygen is large, there is no hydrogen atom directly connected to the electronegativity atom in the carbon dioxide molecule.
According to the conditions for the formation of hydrogen bonds, one needs to have a hydrogen atom and an atom with a large electronegativity and a small radius to be connected by a covalent bond; the other needs to have another atom with a large electronegativity to provide lone pairs of electrons. Both are indispensable. And the carbon dioxide molecule does not satisfy the former, so it can be seen that carbon dioxide does not have hydrogen bonds.
In summary, carbon dioxide does not have hydrogen bonds, which is based on its molecular structure and hydrogen bond formation conditions. Everyone can understand the reasons for the properties of various substances when they study the nature of the structure carefully.
