Final answer:
ICl and CH₃OH can participate in a mutual ion-dipole interaction as they are polar molecules.
Correct option is d.
Step-by-step explanation:
The two species that could participate in a mutual ion-dipole interaction are ICl and CH₃OH.
ICl is polar and exhibits dipole-dipole attractions due to the electronegativity difference between the iodine and chlorine atoms. This allows ICl to interact with ions, forming an ion-dipole interaction.
CH₃OH is also polar and has a high dipole moment, allowing it to interact with ions, particularly with positive ions due to the partially negative oxygen atom.
