Choose the solvent below that would show the greatest freezing point lowering when used to make a 0.20 m nonelectrolyte solution. A) carbon tetrachloride, K_f = 29.9°C/m B) chloroform, K_f = 4.70°C/m C) benzene, K_f = 5.12°C/m D) ethanol, K_f = 1.99°C/m E) diethyl ether, K_f = 1.79°C/m

Question

Quizplus · Accepted Answer

The greater the cryoscopic constant (K_f) of a solvent, the greater the freezing point lowering it will exhibit. Among the given options, carbon tetrachloride has the highest cryoscopic constant (29.9°C/m), indicating the greatest freezing point lowering when used to make a 0.20 m nonelectrolyte solution.
