Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following lists the bonds in order from weakest to strongest?
A
Covalent, Hydrogen, Ionic
B
Hydrogen, Ionic, Covalent
C
Ionic, Covalent, Hydrogen
D
Hydrogen, Covalent, Ionic
Explanation: 

Detailed explanation-1: -Therefore, the order of strength of bonds from the strongest to weakest is; Ionic bond > Covalent bond > Hydrogen bond > Van der Waals interaction.

Detailed explanation-2: -Thus, we will think of these bonds in the following order (strongest to weakest): Covalent, Ionic, Hydrogen, and van der Waals. Also note that in Chemistry, the weakest bonds are more commonly referred to as “dispersion forces.”

Detailed explanation-3: -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.

Detailed explanation-4: -So, in conclusion the ionic bonds are strongest among ionic, covalent and hydrogen bonds.

Detailed explanation-5: -hydrogen bonding, interaction involving a hydrogen atom located between a pair of other atoms having a high affinity for electrons; such a bond is weaker than an ionic bond or covalent bond but stronger than van der Waals forces.
