Sugar molecules dont split further. so if you add a 1:1 ratio of sugar and water, it will have less particles than salt and water causing it to have a higher boiling point
The colligative properties of solutions depend upon the number of molecules dissolved in the solution, but not on the type of solutes. Pure water freezes at 32 F and boils at 212 F. However, adding any kind of solute to pure water will lower the freezing point.
