Consider the 1M aqueous solution of the following compounds and arrange them in the increasing order of elevation in the boiling points.

A. C₆H₁₂O₆

B. NaCl

C. MgCl₂

D. AlCl₃

E. Al₂(SO₄)₃

Choose the correct answer from the options given below:

Explanation:

The elevation of the boiling point of a solution depends on the concentration of solute particles in the solution. The more the number of solute particles in the solution, the higher the elevation in boiling point.

Elevation in boiling point ∝ i × M

The given compounds and their respective aqueous solutions are

\(\begin{array}{lc|c} & \text { Solute } & \mathrm{i} \\ \hline \text { A. } & \mathrm{C}_6 \mathrm{H}_{12} \mathrm{O}_6 & 1 \\ \text { B. } & \mathrm{NaCl} & 2 \\ \text { C. } & \mathrm{MgCl}_2 & 3 \\ \text { D. } & \mathrm{AlCl}_3 & 4 \\ \text { E. } & \mathrm{Al}_2\left(\mathrm{SO}_4\right)_3 & 5 \end{array}\)

Order of elevation in boiling point

E > D > C > B > A
