1. Polarity and Attraction:

* Sugar (sucrose): Sugar molecules are polar, meaning they have a slightly positive end and a slightly negative end due to the arrangement of their atoms.

* Water: Water molecules are also polar, with a slightly positive side near the hydrogen atoms and a slightly negative side near the oxygen atom.

These opposite charges attract each other, like magnets. This attraction is called hydrogen bonding.

2. Disruption of Sugar Structure:

* When sugar is added to water, the water molecules surround the sugar molecules.

* The hydrogen bonds between water molecules and the sugar molecules are stronger than the bonds holding the sugar molecules together.

* This causes the sugar molecules to break apart (dissociate) and become surrounded by water molecules.

3. Diffusion and Hydration:

* The individual sugar molecules now diffuse throughout the water.

* They are essentially "hydrated," meaning they are surrounded and enclosed by water molecules.

4. Solution Formation:

* The result is a homogeneous mixture called a solution. The sugar is now dissolved in the water, and it can't be easily seen anymore.

In summary: Sugar dissolves in water because of the attraction between the polar water molecules and the polar sugar molecules. This attraction is strong enough to break apart the sugar molecules and surround them with water, forming a solution.
