Does Hexane Have Hydrogen Bonding
"On the Existence of Hydrogen Bonds in Hexane"
The nature of a human substance is related to its structure. To determine whether hexane has hydrogen bonds, it is necessary to investigate the molecular structure of its molecules.
Hexane, with the molecular formula of $C_ {6} H_ {14} $, belongs to alkanes. In its molecular structure, carbon and hydrogen are covalently bonded. Carbon atoms are bonded tetravalently, and hydrogen atoms are connected univalently, forming a chain shape.
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 covalently bonding, and another atom with a large electronegativity. In the hexane molecule, only two elements of carbon and hydrogen are formed. The electronegativity of carbon is 2.55, and the electronegativity of hydrogen is 2.20. The difference between the two is not large, and the polarity of the formed carbon-hydrogen bond is weak. And there are no specific atoms that can form hydrogen bonds such as fluorine, oxygen, and nitrogen.
Therefore, it can be seen that hexane does not have hydrogen bonds. Because its molecular structure does not have the necessary conditions for the formation of hydrogen bonds, the intermolecular force is mainly van der Waals force.
