JEE Main & Advanced Chemistry Chemical Bonding and Molecular Structure / रासायनिक आबंधन एवं आणविक संरचना Question Bank Hydrogen bonding

  • question_answer
    Which concept best explains that o-nitrophenol is more volatile than p-nitrophenol                         [AIIMS 1980, 82; Kurukshetra CEE 1998; MP PET 2002]

    A)                 Resonance         

    B)                 Hyperconjugation

    C)                 Hydrogen bonding         

    D)                 Steric hindrence

    Correct Answer: C

    Solution :

                    o-Nitrophenol has intramolecular hydrogen bonding but p-Nitrophenol has intermolecular hydrogen bonding so boiling point of p-Nitrophenol is more than o-Nitrophenol.
