Can CH4 Form Hydrogen Bonds
Whether methane can form hydrogen bonds
hydrogen bonds is a special interaction between molecules, and its formation requires specific conditions. To determine whether methane can form hydrogen bonds, the bonding elements of hydrogen bonds should be analyzed in detail.
The formation of hydrogen bonds requires atoms with large electronegativity and small radius, such as fluorine, oxygen, nitrogen, etc. When these atoms are covalently bound to hydrogen atoms, the hydrogen atom is partially positively charged. Second, another atom with large electronegativity needs to contain lone pairs of electrons in order to attract each other with positively charged hydrogen atoms.
The structure of methane ($CH_ {4} $), carbon and hydrogen are covalently bonded. Although the electronegativity of carbon is slightly larger than that of hydrogen, its electronegativity value is smaller than that of fluorine, oxygen, nitrogen, etc. After bonding with hydrogen, the positive charge density of the hydrogen atom is insufficient. And in the methane molecule, there are no atoms with large electronegativity such as fluorine, oxygen, and nitrogen that contain lone pairs of electrons that can interact with hydrogen atoms.
Therefore, in summary, methane cannot form hydrogen bonds. Due to its structure and composition, it does not meet the necessary conditions for the formation of hydrogen bonds. This is an objective conclusion based on chemical principles.
