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 :
Nucleophile is a species which has high electron density on it and it attack on the site of less electron density. More the electron density on a species better nucleophile it is. Nucleophiles may be neutral (but with an atom with lone pairs of electron) or it can be negatively charged. \[{{C}_{2}}{{H}_{5}}SH\] is the weakest acid so it readily lose a proton to form strong conjugate base \[{{C}_{2}}{{H}_{5}}{{S}^{-}}\] which is a strong nucleophile (\[+1\] effect of \[{{C}_{2}}{{H}_{5}}\] group).
