    Among the following the weakest base is:

    A)  \[{{(C{{H}_{3}})}_{2}}CH{{O}^{-}}\]        

    B)  \[{{(C{{H}_{3}})}_{3}}C{{O}^{-}}\]

    C)                         \[C{{H}_{3}}C{{O}_{2}}C{{H}_{3}}\] 

    D)         \[C{{H}_{3}}C{{O}_{2}}{{C}_{2}}{{H}_{5}}\]

    Correct Answer: C

    Solution :

    \[MnO_{4}^{-}\] is weakest base because \[Mn{{O}_{2}}\] is a strong electron withdrawing group so it reduce electron density on N atom.
