Elektrophils
Elektrophils, commonly spelled electrophiles, are chemical species that seek electrons to form chemical bonds. In Lewis acid–base theory, an electrophile is an electron-pair acceptor. They are typically electron-poor, bear a positive charge, or possess a polarized bond that creates a partial positive center that attracts nucleophiles.
Common examples include protons (H+), carbocations (R3C+), and positively charged metal complexes. Neutral molecules can also
Electrophiles react with nucleophiles, which donate electron density to form covalent bonds. Many reactions proceed via
Hard and soft electrophiles (HSAB theory) describe preferences for nucleophiles of matching character, influencing selectivity and
