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?

Answer»

MOLECULAR mass of X is less than molecular mass of Y
Y is undergoing dissociation in water while X UNDERGOES no change
X is undergoing dissociation in water
Molecular mass of X is greater than the molecular mass of Y

SOLUTION :For EQUIMOLAL solution of two substances, the one that undergoes dissociation produces greater number ofparticles (ions) in the solution and HENCE has greater boilling point.
