Quizplus · Accepted Answer

The water solubility of a compound depends on its polarity and ability to form hydrogen bonds with water molecules. Acetic acid (i) and ethanol (ii) are both polar compounds that can form hydrogen bonds with water molecules, so they are both highly water-soluble. In contrast, benzene (iii) is a nonpolar compound that cannot form hydrogen bonds with water, so it has lower water solubility. Therefore, the correct order of water solubility is (iii) > (ii) > (i).
