A student adds \(10 \text{ mL}\) of liquid hexane, \(\text{C}_6\text{H}_{14}\text{(l)}\), to \(10 \text{ mL}\) of distilled water, \(\text{H}_2\text{O(l)}\), in a test tube at \(25\ ^\circ\text{C}\). After thoroughly shaking the mixture and allowing it to stand, the student observes two separate liquid layers. Which of the following best explains why hexane is immiscible with water?
