Problem

Four liquids are placed in a graduated cylinder in the following order: 10 mL diethyl ether (density 0.71 g mL⁻¹), 10 mL water (density 1.00 g mL⁻¹), 10 mL glycerol (density 1.26 g mL⁻¹), and 10 mL carbon tetrachloride (density 1.59 g mL⁻¹). After vigorous shaking and subsequent settling, the ether remains immiscible with the other liquids, glycerol and water form a single homogeneous solution, and carbon tetrachloride remains immiscible with all others. Which arrangement of layers from top to bottom will most likely be observed? (a) Diethyl ether  /  carbon tetrachloride  /  glycerol–water solution\text{Diethyl ether} \;/\; \text{carbon tetrachloride} \;/\; \text{glycerol–water solution} (b) Diethyl ether  /  glycerol–water solution  /  carbon tetrachloride\text{Diethyl ether} \;/\; \text{glycerol–water solution} \;/\; \text{carbon tetrachloride} (c) Carbon tetrachloride  /  glycerol–water solution  /  diethyl ether\text{Carbon tetrachloride} \;/\; \text{glycerol–water solution} \;/\; \text{diethyl ether} (d) Glycerol–water solution  /  diethyl ether  /  carbon tetrachloride\text{Glycerol–water solution} \;/\; \text{diethyl ether} \;/\; \text{carbon tetrachloride}
