Q. Among the following the strongest nucleophile is
A) $C_{2}H_{5}SH$
B) $CH_{3}COO^{-}$
C) $CH_{3}NH_{2}$
D) $NCCH_{2}^{-}$
Explanation
(a)
Nucleophilies are those substances 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 $+ I\$effect it increases. Hence, higher the $+ I$ effect, higher the nucleophilic power. The +$I$ effect of ethyl is greater than $+ I$ effect of methyl group
