Choose the solvent below that would show the greatest boiling point elevation when used to make a 0.10 m nonelectrolyte solution. A)CCl₄,K_b = 29.9°C/m B)C₆H₆,K_b = 5.12°C/m C)CH₃CH₂OCH₂CH₃,K_b = 1.79°C/m D)CH₃CH₂OH,K_b = 1.99°C/m E)CHCl₃,K_b = 4.70°C/m

Question

Quizplus · Accepted Answer

The boiling point elevation is directly proportional to the molality of the solution and the molal boiling point constant. Since all the solvents are nonelectrolytes and have the same molality, the solvent with the highest molal boiling point constant will show the greatest boiling point elevation. Choice A has the highest molal boiling point constant of 29.9°C/m, making it the best choice.
