    Which of the following solutions will have the highest boiling point?

    A)  1 M glucose solution

    B)  1 M sodium nitrate solution

    C)  1 M barium chloride solution

    D)  1 M aluminium chloride solution

    Correct Answer: D

    Solution :

     \[\text{1 M AlC}{{\text{l}}_{\text{3}}}\]solution will have the highest boiling point is because colligative properties such as elevation in boiling point is directly proportional to number of particles in solutions and \[\text{AlC}{{\text{l}}_{\text{3}}}\] produces highest number of particles or ions.\[(i.e.,\,AlC{{l}_{3}}=1+3=4).\]
