Solutions Question 30

Question: 0.01 molar solutions of glucose, phenol and potassium chloride were prepared in water. The boiling points of

Options:

A) Glucose solution = Phenol solution = Potassium chloride solution

B) Potassium chloride solution > Glucose solution > Phenol solution

C) Phenol solution > Potassium chloride solution > Glucose solution

D) Potassium chloride solution > Phenol solution > Glucose solution

Show Answer

Answer:

Correct Answer: D

Solution:

$ \underset{\text{Boiling point decreasing order }\to }{\mathop{KCl>C_6H_5OH>C_6H_{12}O_6}}, $ Potassium chloride is ionic compound and phenol is formed phenoxide ion hence it is shows greater boiling point then glucose.
