The correct answer is option (D): CO₂, BCl₃, and Fe³⁺. Lewis theory defines an acid as a substance that can accept electron pairs, while a base donates electron pairs. a. It’s a Lewis acid as it accepts electron pairs. b. It isn't a Lewis acid since it does not accept electron pairs, but serves as a base by donating and accepting hydrogen ions. c. This qualifies as a Lewis acid as it accepts electron pairs due to having an incomplete octet and empty 2p orbitals. d. This is categorized as a Lewis acid as it accepts electron pairs. Therefore, the ions recognized as Lewis acids include CO₂, BCl₃, and Fe³⁺.
