Lewis acids are electron pair acceptors, while Lewis bases are electron pair donors, broadening acid–base chemistry to include reactions without protons (e.g., BF3 accepting a lone pair from NH3). This concept explains many organic and inorganic reactions, including complex formation and catalysis (e.g., AlCl3 in Friedel–Crafts alkylation). Lewis acid–base theory is vital for understanding molecular interactions in coordination chemistry.
