Common mistake
Confusing Nucleophiles and Electrophiles
Students often confuse nucleophiles with electrophiles, thinking both are electron donors.
Remember that nucleophiles are electron-rich species that donate electrons, while electrophiles are electron-deficient species that accept electrons. A nucleophile can be defined as a species that has a lone pair of electrons or a negative charge, whereas an electrophile is typically positively charged or has a partial positive charge.
