An aqueous solution of a compound 
freezes at 
. At this temperature, 
behaves as a non-electrolyte. The same solution boils at 
at a pressure of 1 atm (for water, 
) we can conclude that compound 
at the boiling point of solution
A
dimerises completely in solution
B
behaves as a non-electrolyte
C
dissociates in solution
D
ionises to the extent of 
Text Solution
Verified by ExpertsThe correct answer is:
C
As we know, 
On dividing Eqs. (i) by (ii), we get
Since, van't Hoff factor, 
, its a case of dissociation.
