$CH_3^-$

Vedclass · Answer

(C) Nucleophilicity is related to the ability of a species to donate an electron pair. In a given period of the periodic table, nucleophilicity decreases as electronegativity increases. Comparing the atoms $C$, $N$, $O$, and $F$ in the second period: Electronegativity order: $C Therefore, the basicity and nucleophilicity order is: $CH_3^- > NH_2^- > OH^- > F^-$. Thus, $CH_3^-$ is the strongest nucleophile among the given options.
