In relation to every other, covalent bonds room the strongest, complied with by ionic, hydrogen bond, Dipole-Dipole Interactions and Van der Waals forces (Dispersion Forces).
You are watching: Is a hydrogen bond stronger than a covalent bond
Covalent Bonds :
These bonds room the strongest out of the list. This are described as intramolecular bonds, whilst the rest are described as intermolecular forces.
Covalent bonds are the bonds in between atoms created when the atoms share electrons. These bonds create such stability in the atoms, that they often tend to be an overwhelming to break, ultimately making them very strong.
For example, diamonds are very strong, hard and also have a extremely high melting allude due to the the framework of the covalent network and the distribution of the shared electrons between the carbon atoms (covalent bond).
These bonds are the 2nd strongest the end of the list. These take place due to:
For example, sodium chloride is composed of Na+ ions and also Cl- ion bound together.
These are solid and maintained together by the electro-static attraction between the an unfavorable and positively fee ions.
Hydrogen bonds room not accually bonds, and also are accually a specific form of dipole-dipole interaction. They room stronger than usual dipole-dipole They happen due to:
Molecules having a long-term net dipole (difference in electronegativity) native hydrogen gift covalently external inspection to either fluorine, oxygen or nitrogen.
For example, hydrogen binding operate in between water, ammonia and hydrogen fluoride.
I included this come the explanation even thought the wasn"t in the concern as i assumed it is a an extremely important pressure in chemistry. Dipole-Dipole Interactions are stronger than Dispersion forces. They take place due to:
The an ext electronegative atom traction the shared electrons toward itself. That means that one atom has a partial an unfavorable charge, and also the various other atom has actually a partial an unfavorable charge.
For example, H-Cl has actually a dipole as result of the distinction in electronegativity in between the hydrogen atom and also chlorine atom. The electrons spend much more of your time close to the Cl atom.
A dipole-dipole communication is the attraction in between two polar molecules. Once they technique each other, the an adverse end one molecule attractive the positive finish of the other.
Dispersion forces (Van der Waals forces):
Dispersion pressures are really weak forces of attraction. They take place due to:
Momentary dipoles emerging due to uneven electron distributions in adjoining molecules as they method one another.
The weak residual attraction that the nuclei in one molecule for the electron in a neighbouring molecule.

The more electrons that are present in the molecule, the more powerful the dispersion pressures will be.
