    The correct order of basic strength is

    A)  \[{{H}_{2}}O<O{{H}^{-}}<C{{H}_{3}}OH<C{{H}_{3}}{{O}^{-}}\]

    B)  \[C{{H}_{3}}OH<{{H}_{2}}O<C{{H}_{3}}{{O}^{-}}<O{{H}^{-}}\]

    C)  \[{{H}_{2}}O<C{{H}_{3}}OH<O{{H}^{-}}<C{{H}_{3}}{{O}^{-}}\]

    D)  \[O{{H}^{-}}<{{H}_{2}}O<C{{H}_{3}}{{O}^{-}}<C{{H}_{3}}OH\]

    Correct Answer: C

    Solution :

    Strong acids has a weak conjugate base and vice-versa. \[\xrightarrow[Increasing\text{ }order\text{ }of\text{ }basic\text{ }strength]{{{H}_{2}}O<C{{H}_{3}}OH<O{{H}^{-}}<C{{H}_{3}}{{O}^{-}}}\]
