In relation to each other, covalent bonds space the strongest, adhered to by ionic, hydrogen bond, Dipole-Dipole Interactions and also Van der Waals forces (Dispersion Forces).
You are watching: The weak type of bonding which attracts molecules to molecules is:
Covalent Bonds :
These bonds are the strongest the end of the list. These are described as intramolecular bonds, whilst the rest are referred to as intermolecular forces.
Covalent bonds space the bonds in between atoms produced when the atoms share electrons. These bonds develop such security in the atoms, the they have tendency to be difficult to break, ultimately making them really strong.
For example, diamonds are really strong, hard and also have a incredibly high melting point due come the the framework of the covalent network and the distribution of the shared electrons in between the carbon atom (covalent bond).
These bonds room the 2nd strongest the end of the list. These take place due to:
For example, salt chloride is composed of Na+ ions and Cl- ion bound together.
These are solid and retained together through the electro-static attraction in between the an adverse and positively fee ions.
Hydrogen bonds are not accually bonds, and are accually a specific form of dipole-dipole interaction. They space stronger than usual dipole-dipole They occur due to:
Molecules having a permanent net dipole (difference in electronegativity) indigenous hydrogen being covalently external inspection to one of two people fluorine, oxygen or nitrogen.
For example, hydrogen bond operate between water, ammonia and also hydrogen fluoride.
I included this come the explanation even thought the wasn"t in the inquiry as i thought it is a an extremely important force in chemistry. Dipole-Dipole Interactions space stronger 보다 Dispersion forces. They happen due to:
The much more electronegative atom pulls the mutual electrons towards itself. That method that one atom has a partial an unfavorable charge, and the other atom has actually a partial an adverse charge.
For example, H-Cl has a dipole because of the distinction in electronegativity in between the hydrogen atom and also chlorine atom. The electron spend more of their time close to the Cl atom.
A dipole-dipole communication is the attraction between two polar molecules. When they technique each other, the an adverse end one molecule attractive the positive finish of the other.
Dispersion pressures (Van der Waals forces):
Dispersion forces are very weak pressures of attraction. They take place due to:
Momentary dipoles arising due to uneven electron distribution in adjoining 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 stronger the dispersion forces will be.
