As$\mathrm{R}\mathrm{C}{\mathrm{H}}_2^{-},\stackrel{-}{\mathrm{C}}\mathrm{N}$and${\text{CH}}_3{\text{CH}}_2\stackrel{\mathrm{..}}{\underset{\mathrm{..}}{\text{O}}}\text{H}$can donate an electron pair in a reaction so hence, all can act as nucleophiles.
$\mathrm{B}{\mathrm{F}}_3,\mathrm{A}\mathrm{l}\mathrm{C}{\mathrm{l}}_3\mathrm{a}\mathrm{n}\mathrm{d}:\mathrm{C}\mathrm{C}{\mathrm{l}}_2$all electrophiles
