Sugar dissolves faster in H2O than salt because it is more soluable. The soulability of sugar is 211.5 g / 100mL H2O at 20C. NaCl soluability is 39.8 g /100 mL H2O at 25C

Sugar's (assuming you mean sucrose) structure has many -OH groups, which hydrogen bonds easily to water. Water must break up the interaction between sodium and chloride to dissolve salt.

Correct me if I'm wrong, but I believe it would be because ionic bonds (salt) are stronger than covalent bonds (sugar). Thus the weaker covalent bonds break more rapidly.
