    Among the following the strongest acid is:

    A)  \[COC{{H}_{3}}\]

    B)  \[NHCOC{{H}_{3}}\]

    C)  \[C{{H}_{3}}{{O}^{-}}\]

    D)  \[{{C}_{6}}{{H}_{5}}{{O}^{-}}\]

    Correct Answer: B

    Solution :

    \[[V{{({{H}_{2}}O)}_{6}}]S{{O}_{4}}.{{H}_{2}}O\] is   strongest   acid   In \[MnO_{4}^{2-}\] and\[MnO_{4}^{-}\] the \[Mn{{O}_{2}}\] group being electron donating make benzoic acid weaker.
