What needs to happen for a solute to dissolve in a particular solvent?
a) the attractions between the solute and solvent molecules must be greater than the attractions keeping the solute together and the attractions keeping the solvent together.
b) the attractions between the solute and solvent molecules must be greater than the attractions between the solvent particles.
c) the attractions between the solute and solvent molecules must be greater than the attractions between the solute particles.
d) the attractions between the solute and solvent molecules must be less than the attractions keeping the solute together and the attractions keeping the solvent together.

Option (A) is the correct answer.

Explanation:

A solute is defined as the substance which tends to dissolve in another substance. A solute is smaller in amount as compared to the substance in which it is dissolved.

Whereas a solvent is defined as the substance which is present in larger amount as compared to the solute.

So, when a solute is added to a solvent then interaction between both of them is only possible when attraction keeping the solute particles together and attraction keeping the solvent particles together weaken.

This means that greater is the attraction between solute and solvent particles more will be the solubility of the solute particles into the solution.

As a result, solute particles can easily dissociate into ions then.

Thus, we can conclude that for a solute to dissolve in a particular solvent the attractions between the solute and solvent molecules must be greater than the attractions keeping the solute together and the attractions keeping the solvent together.

there all right good
