Vedclass · Answer

(C) nucleophile is a species that donates an electron pair to form a chemical bond. $NH_3$,$OH^-$,and $CN^-$ all possess lone pairs of electrons and can act as nucleophiles. $:CCl_2$ (dichlorocarbene) has an incomplete octet (only $6$ electrons in the valence shell of carbon),which makes it electron-deficient. Therefore,it acts as an electrophile rather than a nucleophile.
