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

    A) \[\text{0}\text{.1 M FeC}{{\text{l}}_{\text{3}}}\]  

    B) \[\text{0}\text{.1 M BaC}{{\text{l}}_{2}}\]

    C)  \[\text{0}\text{.1 M NaCl}\]

    D) \[\text{0}\text{.1}\,\text{M}\,\text{urea}\]

    Correct Answer: A

    Solution :

     \[\text{0}\text{.1}\,\text{M}\,\text{FeC}{{\text{l}}_{\text{3}}}\]will give the maximum number of particles (\[ie,\]ions) in the solution. Hence, its elevation in boiling point is maximum and therefore, it has highest boiling point. \[FeC{{l}_{3}}F{{e}^{3+}}+3C{{l}^{-}}\]
