JEE Main & Advanced Chemistry Solutions / विलयन Question Bank Lowering of vapour pressure

  • question_answer
    When a substance is dissolved in a solvent, the vapour pressure of the solvent is decreased. This results in [MP PMT 1983; NCERT 1981]

    A)                 An increase in the boiling point of the solution

    B)                 A decrease in the boiling point of solvent

    C)                 The solution having a higher freezing point than the solvent

    D)                 The solution having a lower osmotic pressure than the solvent

    Correct Answer: A

    Solution :

                When vapour pressure of solvent decreases, then the boiling point of solvent increases.
