    Which of the following is strongest nucleophile -

    A) \[B{{r}^{-}}\]                  

    B) \[:O{{H}^{-}}\]

    C) \[:C{{N}^{-}}\]            

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

    Correct Answer: C

    Solution :

    The strength of nucleophile depends upon the nature of alkyl group R on which nucleophile has to attack and also on the nature of solvent. The order of strength of nucleophiles follows the order: \[C{{N}^{-}}>{{I}^{-}}>{{C}_{6}}{{H}_{5}}{{O}^{-}}>O{{H}^{-}}>B{{r}^{-}}>C{{l}^{-}}\]
