Is H2O A Hydrogen Bond
Water ($H_2O $) has hydrogen bonds between molecules, which are described in classical Chinese as follows:
If it is water, its molecular formula is $H_2O $. Hydrogen and oxygen are formed by the combination of two elements. Looking at the nature of water, there is a special force between its molecules, which is called hydrogen bond. The cover hydrogen atom is connected to the oxygen atom with a large electronegativity and a small radius. The electron cloud of hydrogen is biased towards oxygen, causing hydrogen to be positively charged, so it attracts the lone pair of electrons of the oxygen atom in the adjacent water molecule. This attraction is the hydrogen bond.
Water has many different properties due to hydrogen bonds. Its boiling point is higher, and water needs more energy to overcome hydrogen bonds than substances with similar molecular weights, so that it can convert from liquid to gaseous state. And its density is maximum when it is 4 dollars ^ {\ circ} C $, which is also the work of hydrogen bonds. When the temperature decreases, the hydrogen bonds between water molecules increase, the arrangement becomes more regular, and the molecular spacing increases, so the density of ice is less than that of water.
From this point of view, there are hydrogen bonds between $H_2O $molecules. This is the root of all the characteristics of water, and is of great significance to natural phenomena and life activities.
