I m not satisfy with this ans. How sugar is most soluble in water I think ans. Is common salt please clear it.

I feel the answer should be common salt.

I am also not satisfied with given ans.

I felt that Ionic compounds are extremely soluble in water than polar covalent compounds sugar soluble in water due to hydrogen bonding whereas salt is purely a ionic compound. So most soluble compound from the given options I felt is common salt.

I think its salt, as it is easily soluble and quicker than sugar!

No, it was wrong. Answer is common salt.

aCl: Water solubility 359 g/L.
Sugar (sucrose) : Water solubility 2000 g/L.
However, if we look at this on a molar basis:
NaCl: Water solubility 359 g/L.
(359 g/L)/(58.44 g/mol) = 6.4 moles/L.
Sugar (sucrose) : Water solubility (2000 g/L).
(2000 g/L)/(342.30 g/mol) = 5.84 moles/L.
So on a molar basis, the solubility are close and one might conclude that the apparent difference lies in the difference in molar masses.
Therefore, SUGAR.

Why the sugar is more soluble than salt give me the answer in a simple way how?

Sugar (sucrose) contains hydroxyl groups that make hydrogen bonds with the solvent (water) , enhancing its solubility over the non-hydrogen-bonding sodium and chloride ions.

I m not feeling comfortable with this answer. I think common salt also can be soluble in water?
