Four 0.50 m aqueous solutions are depicted below. Assume

Solution 94P:

Step 1: (a)

Here, we are going to find out the solution which have the highest boiling point.

Solution A:

It has three particles. Thus, it has the Van’t Hoff factor  3

Solution B and Solution C: Both have two particles

Solution D: It has only one particles.

We know that,

The Van’t Hoff factor is

Thus, the boiling point van't Hoff factor(i).

Therefore, the solution A has the highest boiling point due to its higher van't Hoff factor(i).
