    Correct order of nucleophilicity is

    A) \[CH_{3}^{-}<NH_{2}^{-}<O{{H}^{-}}<{{F}^{-}}\]

    B)  \[{{F}^{-}}<O{{H}^{-}}<CH_{3}^{-}<NH_{2}^{-}\]

    C)  \[O{{H}^{-}}<NH_{2}^{-}<{{F}^{-}}<CH_{3}^{-}\]

    D)  \[{{F}^{-}}<O{{H}^{-}}<NH_{2}^{-}<CH_{3}^{-}\]

    Correct Answer: D

    Solution :

     \[\text{Nucleophilicity}\propto \frac{\text{1}}{\begin{align}   & \text{electronegativity}\,\text{of}\,\text{atom} \\  & \text{bearing}\,\text{negative}\,\text{charge} \\ \end{align}}\]
