Which of the following concept is also known as electron pair-donor acceptor system
Correct answer: B. Lewis
- A. Bronsted-Lowry
- B. Lewis
- C. Lux-Flood
- D. Usanovich
Explanation
The correct answer is the Lewis concept, which is known as the electron pair-donor acceptor system. According to Lewis, an acid is a substance that can accept an electron pair, while a base is a substance that can donate an electron pair. The other options do not specifically focus on electron pairs: Bronsted-Lowry involves proton transfer, Lux-Flood involves oxide ions, and Usanovich is a more generalized theory.
