Sugar is a polar compound and water too a polar solvent. Polar compounds are soluble in polar solvent, and from the options sugar and common salt are polar compounds and sugar is more polar than salt hence sugar dissolves in water.

Sugar is most soluble in water because, it has six hydroxyl groups which mean it can make numerous hydrogen bonds with water, contributing to its high solubility.

@Nikkhil.

I agreed your point they are ionic substances. Thanks.

Here, It should be common salt.

Guys sugar is correct answer because bonds of sugar are weaker than salt that's why sugar is correct answer.

How can sugar be most soluble in water than common salt? Please explain.

As per my knowledge, Sugar is the correct answer.

NaCl: 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) = 6.14 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 solubilities are close and one might conclude that the apparent difference lies in the difference in molar masses.

Therefore, SUGAR.

We know that solid solution are of two type.

1) substitutional solid solution.
2) international solid solution.

In substitutional solid solution, the element that is solute A is distributed in between the solvent B particles.

Again substitution solution is divided into 2 types.

1) order solution.
2) disorder solution.

In order solution, the solute particle arranged in the form of a regular pattern.

Eg sugar with water.

In disorder, the solute atoms dissolve but randomly dissolve in between the solvent atoms.

So, The answer is sugar.

How it can be only sugar not salt?
