JEE Main & Advanced Chemistry Solutions / विलयन Question Bank Elevation of boiling point of the solvent

  • question_answer
    Mark the correct relationship between the boiling points of very dilute solutions of \[BaC{{l}_{2}}\,({{t}_{1}})\] and \[KCl\,({{t}_{2}})\], having the same molarity  [CPMT 1984, 93]

    A)                 \[{{t}_{1}}={{t}_{2}}\]

    B)                 \[{{t}_{1}}>{{t}_{2}}\]

    C)                 \[{{t}_{2}}>{{t}_{1}}\]

    D)                 \[{{t}_{2}}\] is approximately equal to \[{{t}_{1}}\]

    Correct Answer: B

    Solution :

                    \[BaC{{l}_{2}}\] furnishes more ions than \[KCl\] and thus shows higher boiling point \[{{T}_{1}}>{{T}_{2}}\].
