Does H2O2 Have Hydrogen Bonding
The existence of hydrogen bonds in hydrogen peroxide is often related to its microstructure. If we want to investigate whether hydrogen peroxide ($H_ {2} O_ {2} $) contains hydrogen bonds, we need to understand the reason 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 covalent bonding, it is formed with another atom with a large electronegativity and a small radius.
Looking at the structure of hydrogen peroxide, the hydrogen and oxygen in its molecules are connected by covalent bonds. The oxygen atom is quite electronegative, the hydrogen atom is connected to the oxygen, and the electron cloud is biased towards the oxygen, resulting in the positive electricity of hydrogen. The adjacent oxygen atoms in the molecule have high electronegativity and lone pairs of electrons, and the positive hydrogen can form a certain interaction with the lone pairs of electrons of the adjacent oxygen atoms.
From the experimental data, the melting boiling point of hydrogen peroxide is higher than that of substances that generally contain only van der Waals forces. Usually, the melting boiling point of a substance is affected by the intermolecular force, and the van der Waals force is weak. If it has only van der Waals force, its melting boiling point should not be higher. The melting boiling point of hydrogen peroxide is higher, which proves that there is a stronger interaction between its molecules than the van der Waals force, and hydrogen bonds belong to this kind of interaction.
Furthermore, from the perspective of spectral analysis, the existence of specific hydrogen bonds will show a unique absorption peak in the spectrum. When studying hydrogen peroxide spectra, characteristic peaks related to hydrogen bonds can be found, which is also strong evidence for hydrogen bonds in hydrogen peroxide.
In summary, theoretical analysis and experimental evidence show that hydrogen bonds exist between hydrogen peroxide molecules. This conclusion is of great significance for understanding the physicochemical properties of hydrogen peroxide, such as solubility and stability.
