One molal solution of a carboxylic acid in benzene shows the elevation of boiling point of 1.518 K. The degree of association for dimerization of the acid in benzene is (`K_(b)` for beznene = `2.53 K kg mol^(-1)` ):

One molal solution of a carboxylic acid in benzene shows the elevation of boiling point of 1.518 K. The degree of association for simerization of the acid in benzene is ( K_(b) for beznene = 2.53 K kg mol^(-1) ):

The freezing point of benzene decreases by 0.45^(@)C when 0.2 g of acetic acid is added to 20 g of benzene. IF acetic acid associates to form a dimer in benzene, percentage association of acetic acid in benzene will be (K_(f) "for benzene" = 5.12 K kg mol^(-1))

Phenol associates in Benzene to a certain extent to form dimer. A solution containing 2.0 xx 10^(-2) kg of Phenol in 1.0 kg of benzene has its freenzing point decreased by 0.69 K. The percentage degree of association of Phenol is (K_(f) for benzene = 5.12 kg mol^(-1)K)
