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

    A)  \[0.1\,M\,FeC{{l}_{3}}\]                              

    B)  \[0.1\,M\,BaC{{l}_{2}}\]

    C)  \[0.1\,M\,NaCl\]                            

    D)  \[0.1\,M\,urea\]

    Correct Answer: A

    Solution :

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