Question
The van’t Hoff factor, $$i$$ for a compound which undergoes dissociation in one solvent and association in other solvent is respectively.
A.
less than one and less than one
B.
greater than one and less than one
C.
greater than one and greater than one
D.
less than one and greater than one
Answer :
greater than one and less than one
Solution :
Abnormality present due to dissociation and association of the solution.
For dissociation, van’t Hoff factor is greater than one and for association, van’t Hoff factor is less than one.
For dissociation, $$i>1$$
For association, $$i<1$$
