    There is a dynamic equilibrium established between the liquid and the vapour at a given temperature \[\operatorname{Liquid} \,\,vapour\] Which has maximum vapour pressure at a given temperature?

    A)  \[C{{H}_{3}}C{{H}_{2}}C{{H}_{2}}OH\]     

    B)  

    C)  \[C{{H}_{3}}-O-C{{H}_{3}}\]

    D)  \[C{{H}_{3}}COOH\]

    Correct Answer: B

    Solution :

    \[{{\operatorname{CH}}_{3}}OC{{H}_{3}}\] locks H-bonding hence, it is most volatile, so it has maximum vapour pressure.
