Choose the solvent below that would show the greatest boiling point elevation when used to make a 0.10 m nonelectrolyte solution. A) carbon tetrachloride, K_b = 5.03°C/m B) benzene, K_b = 2.53°C/m C) diethyl ether, K_b = 2.02°C/m D) water, K_b = 0.512°C/m E) acetic acid, K_b = 3.07°C/m

Question

Quizplus · Accepted Answer

The boiling point elevation is directly proportional to the molality (m) of the solution and the constant for the solvent (K_b). Therefore, the solvent with the highest K_b value will show the greatest boiling point elevation. Among the given options, carbon tetrachloride has the highest K_b value of 5.03°C/m, indicating that it will show the greatest boiling point elevation when used to make a 0.10 m nonelectrolyte solution.
