Nucleophilic substitution and electrophilic addition reactions Understandings R3.4.1 A nucleophile is a reactant that forms a bond to its reaction partner (the electrophile) by donating both bonding electrons. R3.4.2 In a nucleophilic substitution reaction, a nucleophile donates an electron pair to form a new bond, as another bond breaks producing a leaving group. R3.4.3 Heterolytic fission is ...
