Q.
The electrolyte solutions show abnormal colligative properties. To account for this effect we define a quantity called the Van't Hoff factor given by
Answer the following questions:
$i=\frac{\text {Actual number of particles in solution after dissociation }}{\text { Number of formula units initially dissolved in solution}}$
$i=1$ (for non-electrolytes)
$i >1$ (for electrolytes, undergoing dissociation)
$i< 1$ (for solutes, undergoing association)
Answer the following questions:
Benzoic acid undergoes dimerization in benzene solution. The Van't Hoff factor $i$ is related to the degree of association $\alpha$ of the acid as
