    Which one of the following solutions has the highest\[bp\]?

    A)  \[0.1\text{ }M\,NaCl\]      

    B)  \[0.1\,J\text{ }M\text{ }urea\]

    C)  \[0.1\,M\,BaC{{l}_{2}}\]     

    D)  \[0.1\,M\text{ }glucose\]

    Correct Answer: C

    Solution :

     \[\Delta {{T}_{b}}={{T}_{2}}-{{T}_{1}}\] \[{{T}_{2}}=\]boiling point of solution \[{{T}_{1}}=\] boiling point of solvent For an electrolyte, \[\Delta {{T}_{b}}\propto i\] where, \[i=\]number of ions given in solution. For\[BaC{{l}_{2}},\text{ }i=3,\]which is highest among all other given. Hence,\[BaC{{l}_{2}}\]has maximum boiling point.
