Difference between a Hydrogen Bond and Covalent Bond
The distinction between hydrogen bonds and covalent bonds lies primarily in their mechanism of formation, strength, and the nature of the interaction:
- Formation:
- Covalent bonds form through the sharing of electron pairs between atoms, resulting in a strong bond.
- Hydrogen bonds form due to the attraction between a hydrogen atom bonded to an electronegative atom and another electronegative atom in a different molecule or within the same molecule.
- Strength:
- Covalent bonds are relatively strong and require a substantial amount of energy to break.
- Hydrogen bonds are weaker compared to covalent bonds but stronger than van der Waals forces, which are another type of intermolecular force.
- Nature of Interaction:
- Covalent bonds involve the sharing of electrons, leading to a stable molecular structure.
- Hydrogen bonds are dipole-dipole attractions between molecules or within the same molecule, contributing to the structure and properties of substances such as water, DNA, and proteins.
Hydrogen Bonding
In chemistry, a hydrogen bond is an electrostatic force of attraction between a hydrogen atom and another electronegative atom. It is a special type of dipole-dipole force. Hydrogen bonding is the phenomenon of the formation of Hydrogen Bonds.
H Bonds are stronger than any dipole-dipole bonds but weaker than covalent bonds. Hydrogen bonds can form between atoms within a molecule or between two different molecules.
Hydrogen bonds can form when:
- A hydrogen atom is covalently bonded to a more electronegative atom
- The other atom has a lone pair of electrons
Examples of hydrogen bonds Water, Ammonia, and Hydrogen Fluoride.
