Question
Which of the following has the highest nucleophi-licity?(a) $\mathrm{F}^{-}$(b) $\mathrm{OH}^{-}$(c) $\mathrm{CH}_3^{-}$(d) $\mathrm{NH}_2^{-}$
Step 1
A nucleophile is an electron-rich species that donates electrons to form a bond with an electron-deficient species (electrophile). Nucleophilicity is a measure of how readily a species can donate its electron pair in a reaction. Show more…

Which of the following has the highest nucleophilicity? (a) $\mathrm{F}^{-}$ (b) $\mathrm{OH}^{-}$ (c) $\mathrm{CH}_{3}^{-}$ (d) $\mathrm{NH}_{2}^{-}$
Which of the following is the strongest nucleophile? (a) $\mathrm{NH}_{2}-$ (b) $\mathrm{CH}_{3}-\mathrm{CH}_{2}$ (c) $\mathrm{HC} \equiv \mathrm{C}^{-}$ (d) $\mathrm{H}_{2} \mathrm{C}=\mathrm{CH}^{-}$
