Chemistry - Halogen Derivative Question with Solution | TestHub

Nucleophilicity increases with the decrease in electronegativity of the central atom. Since electronegativity follows the order: $\mathrm{F}>\mathrm{O}>\mathrm{N}>\mathrm{C};$ nucleophilicity of the concerned group will follow the reverse order i.e., ${\mathrm{CH}}_3^{-}>{\mathrm{NH}}_2^{-}>{\mathrm{OH}}^{-}>{\mathrm{F}}^{-}$
