JEE Main & Advanced AIEEE Solved Paper-2009

  • question_answer
    A binary liquid solution is prepared by mixing n-heptane and ethanol. Which one of the following statement is correct regarding the behaviour of the solution?     AIEEE  Solved  Paper-2009

    A) The solution formed is an ideal solution

    B) The solution is non-ideal, showing +ve deviation from Raoult?s Law

    C) The solution is non-ideal, showing -ve deviation from Raoult?s Law

    D) n-heptane shows +ve deviation while ethanol shows -ve deviation from Raoult?s Law.

    Correct Answer: B

    Solution :

    On mixing n-heptane and ethanol; strong interactions are replaced by weak interaction and hence it kes non-ideal solution with positive deviation.
