Hydrogen Bonding Strongest Imf
The hydrogen bond is the strongest intermolecular force
All things in the world, and the force of intermolecular interaction is different, and hydrogen bond is the most powerful among them.
Intermolecular forces are related to many properties of matter, such as melting point, solubility, etc., and have far-reaching effects. Common intermolecular forces include van der Waals forces, which are divided into dispersion forces, induction forces, and orientation forces. These forces are derived from the polarity of molecules and the instantaneous change of electron clouds. However, compared with hydrogen bonds, their strength is much inferior.
The hydrogen bond is a special force formed between a hydrogen atom and an atom with a large electronegativity and a small radius (such as fluorine, oxygen, nitrogen, etc.) after being covalently bonded, and another atom with a large electronegativity. When hydrogen bonds are formed, hydrogen atoms connect two atoms like a bridge, and this unique structure makes the force stronger.
Take water as an example. Water molecules are liquid at room temperature due to hydrogen bonds. If only van der Waals forces are maintained, the boiling point of water should be much lower than it is today, and it may be difficult to exist on earth, and the birth and continuation of life will be in vain. Looking at ammonia again, the hydrogen bonds between ammonia molecules make it unique in similar compounds, such as easy to liquefy and highly soluble in water, all due to the strong hydrogen bond.
Investigate its root cause, the reason why hydrogen bonds are strong is that when they are formed, they involve the special properties of hydrogen atoms. Hydrogen atoms have only one electron. After combining with electronegative large atoms, the electron cloud is strongly biased towards the other side, and the hydrogen nucleus is almost exposed, so it is easy to attract each other with other electronegative large atoms, forming a strong force.
Therefore, among all kinds of intermolecular forces, hydrogen bonds are the strongest, and their influence on the structure and properties of matter is far-reaching and cannot be ignored.
