In relation to each other, covalent bonds are the strongest, followed by ionic, hydrogen bond, Dipole-Dipole Interactions and Van der Waals pressures (Dispersion Forces).
You are watching: Are hydrogen or covalent bonds stronger
Covalent Bonds :
These bonds space the strongest out of the list. These are described as intramolecular bonds, whilst the rest are described as intermolecular forces.
Covalent bonds space the bonds between atoms created when the atoms share electrons. This bonds develop such stability in the atoms, the they tend to be difficult to break, subsequently making them an extremely strong.
For example, diamonds are very strong, hard and also have a extremely high melting point due come the the framework of the covalent network and the circulation of the mutual electrons in between the carbon atom (covalent bond).
These bonds are the 2nd strongest the end of the list. These occur due to:
For example, sodium chloride is composed of Na+ ions and Cl- ion bound together.
These are strong and kept together by the electro-static attraction in between the an adverse and positively fee ions.
Hydrogen bonds room not accually bonds, and also are accually a specific form of dipole-dipole interaction. They space stronger than usual dipole-dipole They happen due to:
Molecules having actually a long-term net dipole (difference in electronegativity) native hydrogen gift covalently external inspection to either fluorine, oxygen or nitrogen.
For example, hydrogen bond operate between water, ammonia and hydrogen fluoride.
I included this to the explanation even thought it wasn"t in the inquiry as i assumed it is a really important force in chemistry. Dipole-Dipole Interactions are stronger than Dispersion forces. They happen due to:
The much more electronegative atom pulls the shared electrons toward itself. That means that one atom has a partial an unfavorable charge, and also the other atom has actually a partial an adverse charge.
For example, H-Cl has actually a dipole as result of the distinction in electronegativity in between the hydrogen atom and chlorine atom. The electron spend an ext of their time near the Cl atom.
A dipole-dipole communication is the attraction between two polar molecules. As soon as they strategy each other, the negative end one molecule attracts the positive finish of the other.
Dispersion forces (Van der Waals forces):
Dispersion forces are very weak pressures of attraction. They happen due to:
Momentary dipoles occurring due come uneven electron distribution in neighbouring molecules together they approach one another.
The weak residual attraction that the nuclei in one molecule because that the electrons in a neighbouring molecule.

The an ext electrons the are present in the molecule, the more powerful the dispersion forces will be.
