Classify and rank order the interactions shown below by thei

Classify and rank order the interactions shown below by their IMF/bond strength, from lowest to highest.

Solution

answer:

B<A<D<C

C is disulfide bond. It is a covalent bond, strongest among all bonds given here.

D is an Ionic bond. It is the attraction between two oppositive charges.

A is a hydrogen bond. It is a weak attraction between the hydrogen atom (which is already bonded to an electronegative atom) of one molecule and an electronegative atom of another molecule.

B is a hydrophobic interaction, weakest among all bonds given here. They are nonpolar and do not interact with water.
