Question

How is colligative property change when solute undergoes association in solution?

Answer 1

Answer:

As A ExaMPle..This increases the molar mass of the solution than expected value, when determined experimentally, using colligative properties methods. When acetic acid (ethanoic acid) is dissolved into benzene, molecules of acetic acid gets associated i.e. dimerize due to hydrogen bondings and number of particles reduced...

Answer 2

Answer:

this increases the molar mass of solute than the expected value

Example_- C6H5COOH undergoes association when dissolved in benzene to form a dimer

so this increases the molar mass of benzoic acid
