Which chemical species acts as a Lewis acid in a chemical reaction?
A. An electron-pair donor
B. A proton donor
C. An electron-pair acceptor✓ Correct Answer
D. A hydroxide ion donor
💡 Solution & Explanation
A Lewis acid is formally defined as a chemical species capable of accepting an electron pair to form a coordinate covalent bond. Conversely, a Lewis base acts as an electron-pair donor, while Brønsted-Lowry acids function specifically as proton donors. Hydroxide ion donors typically characterize Arrhenius bases in aqueous solutions. Chemical bonding and acid-base theories are recurring foundational concepts in general science sections.
