The boiling point of 
solution of 
in water is greater than equimolal solution
of 
in water. Which one of the following statements is true in this case?
is undergoing dissociation in water. 
is greater than the molecular mass of 
.
is less than the molecular mass of 
. 
is undergoing dissociation in water while 
undergoes no change.

Molality of solution 
Molality of solution
We know that, elevation in the boiling point 
of a solution is proportional to the molal concentration of the solution i.e., 
or 
where, 
is the molality of the solution and 
is molal boiling point constant or ebullioscopic constant.
By elevation in boiling point relation
where, 
is van't Hoff factor.
Since, 
of solution 
is greater than 
of solution 
.
(Observed colligative property is greatest than normal colligative property).
of solution 
of solution 
Solution 
undergoing dissociation.
