Why is sugar solluble but sand is not soluble in water? what is the difference in the properties?? please help me

For a liquid to dissolve a solid, the molecules of the liquid and solid must attract one another.

The bond between the oxygen and hydrogen atoms (O–H bond) in sugar (sucrose) gives the oxygen a slight negative charge and the hydrogen a slight positive charge. Sucrose is a polar molecule.

The polar water molecules attract the negative and positive areas on the polar sucrose molecules which makes sucrose dissolve in water.

Sand may be silicon dioxide(silica). Sand is insoluble in water. This is because water cannot break the bonds between silica(sand/SiO2/Silicon dioxide) as it does in sugar. And sand is a non-polar molecule.

Hence sugar is soluble in water while sand is insoluble in water.
