Which one molar solution would have the highest freezing point? A)KCl B)BaCl₂ C)AlCl₃ D)CH₃OH

Question

Quizplus · Accepted Answer

D) CH₃OH is a molecular compound that does not dissociate into ions in solution. The freezing point depression of a solution is dependent on the number of particles in solution. Ionic compounds like KCl, BaCl₂, and AlCl₃ dissociate into multiple ions, increasing the number of particles in solution and thus lowering the freezing point more than a molecular compound like CH₃OH, which does not dissociate.
