Of `0.1` molal solutions of glucose and sodium chloride respectively. Which one will have a higher boiling point?

A

Glucose solution = Phenol solution = Potassium chloride solution

B

Potassium chloride solution `gt` Glucose solution `gt` Phenol solution

C

Phenol solution `gt` Potassium chloride solution `gt` Glucose solution

D

Potassium chloride solution `gt` Phenol solution `gt` Glucose solution

Text Solution

Verified by Experts

The correct Answer is:
D
`underset("Boiling point decreasing order"rarr)(KClgtC_(6)H_(5)OHgtC_(6)H_(12)O_(6))`
Potassium chloride is ionic compound and phenol formed phenoxide ion hence it shows greater boiling point then glucose.
