GENERAL KNOWLEDGE

Detailed explanation-1: -Weakest hydrogen bond will be formed when the electronegativity difference between the atom and H is the least. Hence, S−H−−−−−H form the weakest hydrogen bond.

Detailed explanation-2: -The Hydrogen bonds are the weakest as they aren’t really bonds but just forces of attraction to the dipoles. On a hydrogen atom which are permanent and bonded to two atoms which are highly electronegative in nature. They are just electrostatic and not an actual physical bond which makes them very easy to simply bypass.

Detailed explanation-3: -Therefore, Hydrogen bond is the weakest bond.

Detailed explanation-4: -Hydrogen bonds are weak because they are an ionic interaction between only partially charged molecules. In a covalent bond, orbitals between atoms overlap and the atoms effectively share the electrons. This creates a strong bond that is not easily broken.

Detailed explanation-5: -The hydrogen bonds are less strong than covalent bonds and the van der waals interactions are the weakest. Thus, the order from strongest to weakest is as follows: Ionic bonds > Covalent bonds > Hydrogen bonds > van der waals interactions.
