Chemistry Question from JEE Main 2026 · 28 January, Shift 2

Consider the following aqueous solutions.

I. $2.2 \, \text{g}$ Glucose in $125 \, \text{mL}$ of solution. II. $1.9 \, \text{g}$ Calcium chloride in $250 \, \text{mL}$ of solution. III. $9.0 \, \text{g}$ Urea in $500 \, \text{mL}$ of solution. IV. $20.5 \, \text{g}$ Aluminium sulphate in $750 \, \text{mL}$ of solution.

The correct increasing order of boiling point of these solutions will be: [Given: Molar mass in $\text{g mol}^{-1}$: H = $1$, C = $12$, N = $14$, O = $16$, Cl = $35.5$, Ca = $40$, Al = $27$ and S = $32$]
