    Among the following the strongest nucleophile is

    A) \[{{C}_{2}}{{H}_{5}}SH\]

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

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

    D) \[NCCH_{2}^{-}\]

    Correct Answer: A

    Solution :

    Nucleophiles are thosesubstances which can donate a pair of electrons/They can be neutral or negatively charged. The nucleophilic power depends on the tendency of species to donate the electrons. Due to the presence of +/ effect, it increases. Hence, higher the +/ effect, higher the nudeophilic power.
