An aqueous solution of a compound AB freezes at 
. At this temperature, AB
behaves as a non-electrolyte. The same solution boils at 
at a P of 1 atm (for water, 
) we can conclude that compound AB at the boiling point of solution,
A
Behaves as a non-electrolyte
B
Ionises to the extent of 
C
Dimerises completely in solution
D
Dissociates in solution
Text Solution
Verified by ExpertsThe correct answer is:
D
Apply, 
…… ..(i)
…… ..(ii)
On dividing eq. (i) and (ii), we get
Since, van't hoff factor, 
, its a case of dissociation.
