In case of electrolyte which dissociates in the solution the van Hoff factor I

When an electrolyte is dissociated in solution, the van.t Hoffs factor (i) is ,

In case a solute associates in solution, the van't Hoff factor,

The van't Hoff factor i for an electrolyte which undergoes dissociation in one solvent and association in other solvent respectively:

For solutes which do not undergo any association or dissociation in a solute, van't Hoff factor (i) will be

For a non-electrolyte solution, the Van't Hoff factor is equal to

The electrolyte solutions show abnormal colligative porperties.To account for this effect we define a quantity called the Van't Hoff factor given by i=("Actual number of particles in solution after dissociation")/("Number of formula units initially dissolved in solution") i=1 ("for non-electrolytes") igt1 ("for electrolytes, undergoing dissociation") ilt1 ("for solutes, undergoing association") Answer the following questions: Benzoic acid undergoes dimerization in bezene solution. The Van't Hoff factor i for the solutions is
