In relationship to every other, covalent bonds room the strongest, complied with by ionic, hydrogen bond, Dipole-Dipole Interactions and also Van der Waals forces (Dispersion Forces).
You are watching: Hydrogen bonds are stronger than covalent bonds
Covalent Bonds :
These bonds are the strongest out of the list. These are referred to as intramolecular bonds, whilst the rest are referred to as intermolecular forces.
Covalent bonds room the bonds in between atoms created when the atoms share electrons. These bonds produce such stability in the atoms, the they often tend to be complicated to break, subsequently making them an extremely strong.
For example, diamonds are an extremely strong, hard and also have a incredibly high melting point due to the the structure of the covalent network and the circulation of the common electrons between the carbon atoms (covalent bond).
These bonds are the second strongest the end of the list. These happen due to:
For example, salt chloride consists of Na+ ions and Cl- ion bound together.
These are solid and preserved together by the electro-static attraction in between the negative and positively charged ions.
Hydrogen bonds are not accually bonds, and also are accually a specific kind of dipole-dipole interaction. They space stronger than typical dipole-dipole They take place due to:
Molecules having actually a irreversible net dipole (difference in electronegativity) from hydrogen gift covalently bonded to either fluorine, oxygen or nitrogen.
For example, hydrogen bonds operate in between water, ammonia and also hydrogen fluoride.
I added this come the explanation even thought that wasn"t in the inquiry as i believed it is a really important force in chemistry. Dipole-Dipole Interactions are stronger than Dispersion forces. They take place due to:
The much more electronegative atom pulls the shared electrons toward itself. That means that one atom has a partial an adverse charge, and also the other atom has actually a partial negative charge.
For example, H-Cl has a dipole due to the distinction in electronegativity between the hydrogen atom and chlorine atom. The electrons spend an ext of your time near the Cl atom.
A dipole-dipole interaction is the attraction in between two polar molecules. When they approach each other, the an adverse end one molecule attracts the positive end of the other.
Dispersion pressures (Van der Waals forces):
Dispersion forces are an extremely weak pressures of attraction. They take place due to:
Momentary dipoles emerging due come uneven electron distributions in neighbouring molecules as they technique one another.
The weak residual attraction of the nuclei in one molecule because that the electrons in a adjoining molecule.

The much more electrons that are current in the molecule, the more powerful the dispersion forces will be.
