Gilbert N. Lewis formulated which theory of acid-base reactions?

• A. Bronsted-Lowry theory
• B. Electron-pair theory
• C. Arrhenius theory
• D. Lewis acid-base theory

Answer: (B)

Gilbert N. Lewis introduced an approach to acid–base chemistry based on electron pairs: acids accept an electron pair, while bases donate one. This perspective explains many reactions beyond proton transfer, such as NH3 donating its lone pair to BF3 to form a coordinate bond. The framework is widely known as Lewis acid-base theory, even though the idea is sometimes described simply as electron-pair theory; the canonical name emphasizes the electron-pair donation/acceptance relationship.
