You've got it in reverse. When sucrose dissolves in water, sucrose is the solute, and water is the solvent. In order to dissolve, sucrose molecules have to be more attracted to water molecules than they are to other sucrose molecules. If the attraction of sucrose to sucrose was greater than the attraction of sucrose to water, then there would be no reason for the solid sucrose to turn into the aqueous sucrose solution. Sucrose molecules would simply remain firmly attached to each other if that were the case.

The attractive force between like particles is called cohesion. It is the force that holds similar particles together within a substance.

It is a decrease.
Potential energy results from the attractive forces between particles. This potential energy represents the stored energy that can be released when the particles move closer together.

At room temperature, the greatest attractive forces exist between particles of solids because the particles are closely packed together and have strong intermolecular forces such as Van der Waals forces or hydrogen bonding.

Charged particles exert an electric force on other charged particles in their vicinity. This force can either be attractive (between particles of opposite charge) or repulsive (between particles of the same charge).

D. Particles exert attractive forces. In real gases, the particles do not always move in the same direction, have the same kinetic energy, or have difficulty diffusing due to interactions between the particles leading to attractive forces that are not present in ideal gases.
The particles in the solid (solute) break apart and form links with the particles in the liquid (solvent). There are strong forces of attraction between the molecules and particles inside the solute. These forces keep the particles together and make the solute a solid because they attract the solute particles tightly together. There are also strong forces of attraction between the molecules and particles inside the solvent. These forces keep the particles together and make the solvent a liquid because they attract the solvent particles slightly together. There is also an attractive force between the solute and solvent particles. To break these forces and from a bond between the solute and solvent particles energy is needed. This energy is gained from heat (the process of dissolving is speeded up through heat.) In conclusion, the particles in a solute break apart of their attractive forces and form bonds with the solvent particles through the attraction between the solute and solvent particles and through the energy gained by heat.
Gases consist of freely moving particles due to their high kinetic energy. The distance between gas particles is typically large, and the attractive forces between them are usually negligible. In the gas phase, the kinetic energy of the particles overcomes any weak intermolecular forces that may exist.
