Hydrogen Bonds Formation between Water Molecules
Water is the source of all things, and the formation of hydrogen bonds between its molecules is worthy of in-depth study. Water molecules are composed of hydrogen and oxygen, and hydrogen and oxygen are connected by covalent bonds. However, the electronegativity of oxygen is stronger than that of hydrogen, so the electron cloud of hydrogen-oxygen covalent bonds is biased towards oxygen atoms, causing hydrogen atoms to be slightly positive and oxygen atoms to be slightly negative.
When a slightly positive hydrogen atom of one water molecule approaches a slightly negative oxygen atom of another water molecule, a weak interaction occurs between the two, which is a hydrogen bond. Although the force of hydrogen bonds is inferior to covalent bonds, it has a profound impact on the many properties of water.
The formation of hydrogen bonds makes water molecules attract each other and form a specific arrangement. In the liquid state, hydrogen bonds continue to form and break, maintaining the polymerization force of water molecules, causing water to have a higher boiling point and melting point. If hydrogen bonds do not exist, the boiling point of water will be much lower than it is today, and it is difficult for the earth to have liquid water, and it is impossible to breed life.
And hydrogen bonds also play a key role in the surface tension and specific heat of water. On the surface of water, due to hydrogen bonds, water molecules pull each other to form a film-like structure that can support light objects, which is a manifestation of surface tension. When hydrogen bonds absorb and release heat, they need to consume or release energy, which makes the specific heat of water larger and can effectively adjust the ambient temperature.
In summary, the formation of hydrogen bonds between water molecules is the root of many unique properties of water, which has a great impact on the growth and reproduction of all things in nature.
