II. C₆H₆
III. H₂O

Question

Which of the following molecular compounds would be highly soluble in hexane, C₆H₁₄? I. CH₃OH II. C₆H₆ III. H₂O

Quizplus · Accepted Answer

Hexane is a nonpolar solvent, so it will dissolve nonpolar compounds better than polar compounds. Compound II is a nonpolar compound because it consists of only carbon and hydrogen atoms. Compounds I and III are polar compounds because they contain oxygen atoms, which are more electronegative than carbon and hydrogen atoms. Therefore, only compound II (C₆H₆) would be highly soluble in hexane.
