Question

Rank the following solutions in order of increasing boiling point: 2.5 m fructose, C₆H₁₂O₆ 2.0 m NaCl 1.5 m methanol, CH₃OH 2.2 m Al(NO₃)₃ A)C₆H₁₂O₆ < Al(NO₃)₃ < NaCl < CH₃OH B)CH₃OH < Al(NO₃)₃ < NaCl < C₆H₁₂O₆ C)Al(NO₃)₃ < NaCl < C₆H₁₂O₆ < CH₃OH D)CH₃OH < C₆H₁₂O₆ < NaCl < Al(NO₃)₃ E)CH₃OH < C₆H₁₂O₆ < Al(NO₃)₃ < NaCl

Quizplus · Accepted Answer

The boiling point elevation depends on the number of particles in solution. Al(NO3)3 dissociates into 4 ions, NaCl into 2 ions, while fructose and methanol do not dissociate. Thus, Al(NO3)3 has the highest boiling point, followed by NaCl, then fructose, and methanol has the lowest.
