As we learned

 

Vant Hoff factor for dissociation -

i=1-\alpha +\frac{\alpha }{n}

n= number of particles associated

\alpha = degree of association

e.g. Carboxylic acid dimerized in non polar solvents like Hexane.
 

- wherein

n = 2 for dimerization

n = 3 for trimerization

 

 Benzoic acid in benzene undergoes association through intermolecular hydrogen bonding.
