Answer
Sucrose molecules form crystals but the bonds that hold the sucrose molecule together are not non-polar{ the oxygen end of the O-H bonds are +ve and the hydrogen is mildly -ve.. The water molecules ( the solute) are also polar with lone electron pairs and polar hydrogen bonds. The water molecule can therefore attract bot the positive and negative poles of sucrose molecules and pull the crystals apart. this results in easy separation( solution ) of the sucrose molecules.
Work Step by Step
The polar water molecules are attracted to the polar sucrose molecules. The molecules bind easily and because of volume and energy differentials the water molecules are able to tear the sucrose crystals apart and surround them with water shells that prevent them from reuniting.
