Acetic acid dimerizes when dissolved in ...

Acetic acid dimerizes when dissolved in benzene. As a result boiling point of the solution rises by `0.36^(@)C` , when 100 g of benzene is mixed with ''X'' g of acetic acid. In this solution, if experimentally measured ,measured molecular weight of acetic acid is,117.8 and molar elevation constant of benzene is I `2.57 K kg mol^(-1)` what is the weight and degree of dissociation (in %) of acid in benzene?

A

1.62 and 98.3

B

0.81 and 98.3

C

0.5 and 86

D

1 and 98.3
