Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which is the strongest non covalent bond?
A
hydrogen bond
B
dipole-dipole interaction
C
ionic interaction
D
London dispersion force
Explanation: 

Detailed explanation-1: -The ion-ion, dipole-dipole, and ion-dipole interactions between oppositely charged particles is the strongest non-covalent bond.

Detailed explanation-2: -The strongest type of non-covalent interaction is between two ionic groups of opposite charge (an ion-ion or charge-charge interaction).

Detailed explanation-3: -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-4: -Covalent and noncovalent bonds differ in their strength. Covalent bonds, resulting from the sharing of an electron pair between two atoms are the strongest. Noncovalent interactions are somewhat weaker.

Detailed explanation-5: -Of the non-covalent interactions, ionic are the strongest, while van der Waals are the weakest. It is important to note that many weak interactions can sum to form a powerful interaction. In fact, this is crucial to the structure of many proteins in the human body.
