Can H2O Form Hydrogen Bonds
Whether water ($H_2O $) can form hydrogen bonds
Water ($H_2O $) is the softest thing in the world, but its properties are special. Hydrogen bonds, non-chemical bonds, are weak interactions between molecules. Although the force is small, it has a huge impact on the properties of substances.
Looking at the structure of water, hydrogen and oxygen are connected by covalent bonds. The electronegativity of oxygen is strong, and the electron cloud is biased towards oxygen, causing hydrogen to be positively charged. The oxygen in the adjacent water molecule has a lone pair of electrons, which is partially negatively charged, and attracts each other with the positive hydrogen, which is the formation of hydrogen bonds.
With common sense, water can indeed form hydrogen bonds. Many of the abnormalities of water depend on the work of hydrogen bonds. If the boiling point is different, the hydrogen bond increases the intermolecular force, and the gasification needs more energy; the density of ice is less than that of water, because the hydrogen bond makes the water molecules in ice form a regular tetrahedral structure and the gap increases.
From this perspective, water ($H_2O $) can actually form hydrogen bonds, which is the main reason why it plays a key role in the biochemistry of all things.
