You are correct. Sugar is a non-polar compound because it does not ionize; that is, it dissolves in water but stays as the molecule instead of breaking apart into ions as NaCl (salt) does.

Thanks a lot!
Also one more question..
What general rule determines whether a solute will dissolve in a solvent?
Thanks!

Remember the saying, “like dissolves like.” That is, polar compounds, in general, dissolve in polar solvents and non-polar compounds dissolve in non-polar solvents. Salt is a polar compound and dissolves in water, a polar solvent. Sugar also dissolves, easily, in water although sugar is a non-polar compound and water is a polar solvent? Why? Because sugar has a lot of OH groups on it and water is H2O or HOH.
