The boiling point of `0.2 mol kg^(-1)` solution of `X` in water is greater than equimolal solution of `Y` in water. Which of the following statements is true in this case?

A

Molecular mass of X is less than molecular mass of Y

B

Y is undergoing dissociation in water while X undergoes no change

C

X is undergoing dissociation in water

D

Molecular mass of X is greater than the molecular mass of Y

Text Solution

Verified by Experts

The correct Answer is:
C

For equimolal solution of two substances, the one that undergoes dissociation produces greater number of particles (ions) in the solution and hence has greater boilling point.
