Are Hydrogen Bonds The Strongest
On the strength of hydrogen bonds
In the world of chemical bonds, there are many doubts about the strength of hydrogen bonds. Or ask: Is the hydrogen bond the strongest bond?
To understand this, we should observe the properties of all chemical bonds. Chemical bonds are also the force of the phase between atoms. Common ones include ionic bonds, covalent bonds, and metal bonds, which are all maintained by the transfer, sharing, or delocalization of electrons between atoms.
Ionic bonds, anions and cations are electrostatically attracted to form bonds, and their forces are quite huge. For example, in the genus sodium chloride, the ionic lattice is strong and the melting point is quite high. The force of this ionic bond is caused. The covalent bond between atoms shares an electron pair to achieve a stable structure, such as hydrogen molecules, each hydrogen atom has an electron shared in it, and the bond energy can also be observed, so that the molecule has a certain stability. The metal bond is the delocalization of the valence electrons of the metal atom, forming an electron gas, gluing the metal ions, resulting in good electrical conductivity, thermal conductivity and ductility of the metal.
As for the hydrogen bond, its formation is different from the above 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, and nitrogen) after covalently binding, and another atom with a large electronegativity. Although it is called a "bond", its force is weaker than that of ionic bonds, covalent bonds, and metal bonds.
Take water as an example, there are hydrogen bonds between water molecules. The boiling point of water is higher than that of hydrogen sulfide, because hydrogen bonds enhance the force between water molecules. However, when water is heated into steam, hydrogen bonds are easily broken, which shows that the power of hydrogen bonds is not as good as covalent bonds. If the covalent bond breaks when water is heated, the water will no longer be water, but will become hydrogen and oxygen elementals, which requires much more energy than the ability to break hydrogen bonds.
In summary, hydrogen bonds are not the strongest bonds. Although in some systems, hydrogen bonds have a significant impact on the properties of substances, the strength of the bonds is not as good as ionic bonds, covalent bonds, metal bonds, etc. Each chemical bond has its own characteristics, and each performs its own role in the structure and properties of matter, co-constructing the diverse and colorful world of matter.
