$CH_3^-$

Vedclass · Answer

(C) Nucleophilicity is the ability of a species to donate an electron pair to an electrophile. In a period of the periodic table,nucleophilicity decreases as electronegativity increases. The electronegativity order of the atoms bearing the negative charge is $C Since $CH_3^-$ has the least electronegative atom $(C)$,it holds its lone pair the least tightly and is therefore the best nucleophile. Thus,the order of nucleophilicity is $CH_3^- > NH_2^- > OH^- > F^-$.

Which of the following has the highest nucleophilicity?
