The solvent that would have the highest boiling point when used to make a 0.10 m nonelectrolyte solution is the one with the highest boiling point elevation constant KbK_bKb. From gathered data, solvents have these approximate molal boiling point elevation constants:
- Carbon tetrachloride: Kb≈5.03K_b\approx 5.03Kb≈5.03 °C/m
- Benzene: Kb≈2.53K_b\approx 2.53Kb≈2.53 °C/m
- Diethyl ether: Kb≈2.02K_b\approx 2.02Kb≈2.02 °C/m
- Water: Kb≈0.512K_b\approx 0.512Kb≈0.512 °C/m
Among these, carbon tetrachloride has the highest KbK_bKb value, meaning a 0.10 m solution in carbon tetrachloride will have the greatest boiling point elevation and thus the highest boiling point.
Hence, carbon tetrachloride is the solvent that would show the highest boiling point in a 0.10 m nonelectrolyte solution.
