Polar Covalent Bond vs Hydrogen Bond
"Differentiation between Polar Covalent Bonds and Hydrogen Bonds"
A taste of chemical principles. There are polar covalent bonds and hydrogen bonds. Although both involve the interaction between atoms, their properties are completely different.
Polar covalent bonds are atoms that combine in a common electron pair. Due to the difference in atomic electronegativity, the electron pair is biased towards the electronegative strong, so the bond is polar. The force of this bond is derived from the atom's attraction to the common electron, maintaining the basic structure of the molecule. Its energy is large, and the molecule depends on it to survive.
As for hydrogen bonds, it is not strictly chemical bonds, but the weak interaction between hydrogen atoms with strong polar bonds and atoms with large electronegativity and lone pairs of electrons. The force of hydrogen bonds is weaker than that of polar covalent bonds, but it has a significant impact on many properties of substances. For example, in water, due to hydrogen bonds, the boiling point of water is abnormally high, and the density of ice is lower than that of water. This is all due to the work of hydrogen bonds.
Polar covalent bonds determine the internal structure and basic stability of molecules, while hydrogen bonds are weak, but they have a significant impact on intermolecular interactions, aggregation states of substances, and special physical and chemical properties. The two complement each other, and the polymorphism and properties of co-constitutive substances are of paramount importance in the field of chemistry. Only by clarifying them can we understand the secrets of the microscopic world of chemistry.
