The molecules or ions that can acts as nucleophile in nucleophilic substitution reactions have to be given. Concept Introduction: Nucleophile: A chemical species that donates an electron pair to form a chemical bond is called as nucleophile. All molecules or ions with a lone pair of electrons or atleast one pi bond acts as nucleophile. Since nucleophiles donate electrons, they are Lewis bases. Nucleophiles may take part in a nucleophilic substitution reaction, whereby a nucleophile becomes attracted to a full or partial positive charge. Electrophile: A chemical species that accepts an electron pair are called as electrophiles. Electrophiles are positively charged or neutral species having vacant orbitals that are attracted to an electron rich center. It takes part in chemical reaction by accepting an electron pair in order to bond to a nucleophile.
