Question

What are the strongest to weakest bonds?

Answer 1

Hint: Covalent bonds are known to be the strongest and the bonds formed via Van der Waals forces are known to be the weakest. The ranking from strongest to weakest bonds is: Covalent bond $>$ ionic bond $>$ hydrogen bond $>$ Van der Waals forces.

Complete answer: The order from strongest to weakest bonds is: Covalent bond $>$ ionic bond $>$ hydrogen bond $>$Van der Waals forces.
Covalent bond: the interatomic linkage that results from the sharing of an electron pair between two atoms. The binding arises from the electrostatic attraction of their nuclei for the same electrons
Ionic bond: Ionic bonds involve a cation and an anion. The bond is formed when an atom, typically a metal, loses an electron or electrons, and becomes a positive ion, or cation. One example of an ionic bond is the formation of sodium fluoride, from a sodium atom and a fluorine atom.
Hydrogen bond: Hydrogen bonding is a special type of dipole-dipole attraction between molecules, not a covalent bond to a hydrogen atom. It results from the attractive force between a hydrogen atom covalently bonded to a very electronegative atom.
Van der Waals bond: Van der Waals forces include attraction and repulsions between atoms, molecules, and surfaces, as well as other intermolecular forces. They differ from covalent and ionic bonding in that they are caused by correlations in the fluctuating polarizations of nearby particles

Note:
The weakest bonds are commonly referred to as dispersion forces. The dispersion force is a temporary attractive force that results when the electrons in two adjacent atoms occupy positions that make the atoms form temporary dipoles. Dispersion forces are present between any two molecules when they are almost touching.
