A bottle of rubbing alcohol contains both 2-propanol and water, which can be separated by distillation due to their differing boiling points. 2-Propanol (isopropyl alcohol) has a boiling point of about 82.6°C, while water boils at 100°C. During distillation, the lower boiling component (2-propanol) vaporizes first and can be collected separately upon condensation, effectively separating it from the water. This process exploits the physical property of volatility to achieve separation.
