Answer:
carbon tetrachloride
Step-by-step explanation:
Boiling point elevation of a liquid or a compound is defined as the boiling point of a liquid that is that will be higher when some other other compound is added. It means that the solution has a higher boiling point than the solvent. When a non volatile solute is added to the pure solvent like water, it results in the highest boiling point elevation.
Carbon tetrachloride, Kb = 5.03°C/m shows highest boiling point elevation when it is used to make a 0.10 m non - electrolyte solution.
