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_fwill, 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.Shall we obtain a abnormal molar mass if we determine the boiling point of glucose solution ?

Answer»

SOLUTION :YES, ABNORMAL molar mass will be OBTAINED.
