JEE Main 2026 (28 January Shift 2)
Question
Consider the following aqueous solutions.
I. 2.2 g Glucose in 125 mL of solution.
II. 1.9 g Calcium chloride in 250 mL of solution.
III. 9.0 g Urea in 500 mL of solution.
IV. 20.5 g Aluminium sulphate in 750 mL of solution.
The correct increasing order of boiling point of these solutions will be :
[Given : Molar mass in and ]

Correct answer
B
Step-by-step explanation
For dilute solution ()
| Molarity | |
|---|---|
| (I) | |
| (II) | |
| (III) | |
| (IV) |
Order of = > Urea > > Glucose
So order of BP = > Urea > > Glucose
So Answer will be I < II < III < IV
