The boiling point of 0.2 mol kg^(-1) sol...

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

A

Molecular mass of X is less than the 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
`DeltaT_b= ik_b m`
For equimolal solutions, elevation in boiling point will be higher, if solution undergoes dissociation i.e., `i gt 1`.
