Classify the substances according to the strongest solute-solvent interaction that will occur between the given substances and water during dissolution.

a. CuCl2
b. CuSO4
c. NH3
d. CH3OH

Explanation:

Ion-dipole interactions are defined as the interactions that occur when an ion interacts with the dipole of a molecule (polar molecule).

For example, , , , NaCl etc are all the molecules that will show ion-dipole interactions.

Dipole-dipole interactions are defined as the interactions that occur when partial positive charge on an atom is attracted by partial negative charge on another atom.

When a polar molecules produces a dipole on a non-polar molecule through distribution of electrons then it is known as dipole-induced forces.

For example, , etc are the molecules which show dipole-dipole interactions.
