Hydrogen bond between two atoms is formed due toa)Displacement of elec...
Hydrogen bond between two atoms is formed due to displacement of electrons towards more electronegative atom resulting in fractional positive charge on hydrogen.
Explanation:
Hydrogen bond is a type of intermolecular force that occurs between a hydrogen atom and an electronegative atom. It is a relatively weak bond, but it plays a crucial role in many biological and chemical processes.
Displacement of electrons towards more electronegative atom:
In a hydrogen bond, the hydrogen atom is covalently bonded to a highly electronegative atom such as oxygen, nitrogen, or fluorine. These electronegative atoms have a stronger pull on the shared electrons, causing them to be displaced towards the electronegative atom.
Fractional positive charge on hydrogen:
As the electrons are displaced towards the more electronegative atom, the hydrogen atom becomes partially positive due to the electron deficiency. This creates a partial positive charge on the hydrogen atom.
Role of electronegativity:
Electronegativity is the measure of an atom's ability to attract electrons towards itself in a chemical bond. The greater the electronegativity difference between two atoms, the stronger the hydrogen bond. This is because a larger electronegativity difference results in a larger displacement of electrons, creating a larger partial positive charge on the hydrogen atom.
Importance of hydrogen bonding:
Hydrogen bonding plays a crucial role in many biological processes and chemical reactions. Some important functions of hydrogen bonding include:
1. Stabilizing the structure of biomolecules: Hydrogen bonds help in maintaining the three-dimensional structure of proteins, DNA, and RNA. They contribute to the stability of alpha helices and beta sheets in proteins and the double helix structure of DNA.
2. Solubility of polar substances: Hydrogen bonding facilitates the solubility of polar substances in water. Water molecules form hydrogen bonds with polar solute molecules, allowing them to dissolve.
3. High boiling and melting points: Substances with hydrogen bonding have higher boiling and melting points compared to substances without hydrogen bonding. This is because the energy required to break the hydrogen bonds is higher.
4. Surface tension and capillary action: Hydrogen bonds contribute to the high surface tension of water and capillary action. Water molecules at the surface form stronger hydrogen bonds with neighboring molecules, creating a "skin" on the surface.
In conclusion, a hydrogen bond between two atoms is formed due to the displacement of electrons towards the more electronegative atom, resulting in a fractional positive charge on the hydrogen atom. This type of intermolecular force plays a crucial role in various biological and chemical processes.
