Arrange the compounds in order of increasing solubility in water (least first).

Question

Quizplus · Accepted Answer

Compounds III and IV are both salts, which are generally more soluble in water than organic compounds like I and II. Among the salts, compound III is likely less soluble because it has a larger, more complex ion (Fe(CN)6) compared to compound IV which has a smaller chloride ion. Among the organic compounds, I is likely less soluble because it is non-polar and therefore does not interact as strongly with water molecules as polar compound II. Therefore, the correct order of increasing solubility is III, IV, I, II.
