Can anyone help me with this question

Question

The value of ∆Hsoln for the formation of an acetone – water solution is negative. Explain this in general terms that discuss intermolecular forces of attraction.

Answer 1

A negative ∆H_soln means that heat is given off to the surroundings upon dissolution of the acetone in the water. What happens during this process, in the simplest of terms, is that the intermolecular forces holding the acetone molecules together must be broken and this process requires an input of energy so it is endothermic (∆H is positive). At the same time, the intermolecular forces holding the water molecules together must be broken and again this is endothermic (∆H is positive). Finally, the molecules of acetone and water interact to form the solution, and this process is exothermic as energy is released (∆H is negative). When you add up the ∆H from these 3 processes, you get the ∆H_soln. In this case, the ∆H is negative which simply means that more heat energy is given off than it takes to break apart all the intermolecular forces holding the solute and solvent molecules together.

Side note: Intermolecular forces holding acetone molecules together consist mainly of dipole-dipole interactions. Intermolecular forces holding water molecules together consist mainly of hydrogen bonds.

I hope this makes sense.
