Understand the terms nucleophile and electrophile, and recall why these concepts are important in chemical reactions. ELECTROPHILE: electron pair acceptor. Often carry a partial positive charge. E.g. H+ NUCLEOPHILE: electron pair Sometimes carrying a partial negative charge. E.g. Cl-. Double and triple bonds are nucleophilic. e.g. Acid-base reaction. Brønsted-Lowry Nucleophilic substitution nucleophile in and leaving out. – - Nucleophilic addition Electrophilic addition double bond acting as a nucleophile, formation of a carbocation. –
