0.01 molar solutions of glucose, phenol ...

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

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.)(KCl gt C_(6)H_(5)OH gt C_(6)H_(12)O_(6))`
Potassium chloride is ionic compound and phenol formed phenoxide ion hence it shows greater boiling point then glucose.
