Read the given passage and answer the questions : Molecules of ethanoic acid dimerise in benzene due to hydrogen bonding. This normally happens in solvents of low dielectric constant. In this case, the number of particles is reduced due to dimerisation. The molar mass calculated on the basis of this Delta T_b or Delta T_f will, therefore, be twice the expected value. Such a molar mass that is either lower or higher than the expected or normal value is called as abnormal molar mass. Why does ethanoic acid dimerise in benzene solution ?
