Identify the Lewis acid, Lewis base, and Lewis acid-base adduct in the following equation: (C₂H₅)₂O + BF₃ ⇌ (C₂H₅)₂O:BF₃ A) (C₂H₅)₂O is a Lewis base, BF₃ is a Lewis acid, and (C₂H₅)₂O:BF₃is a Lewis acid-base adduct. B) (C₂H₅)₂O is a Lewis acid, BF₃ is a Lewis base, and (C₂H₅)₂O:BF₃is a Lewis acid-base adduct. C) (C₂H₅)₂O is a Lewis acid-base adduct, BF₃ is a Lewis acid, and (C₂H₅)₂O:BF₃is a Lewis base. D) (C₂H₅)₂O is a Lewis base, BF₃ is a Lewis acid-base adduct, and (C₂H₅)₂O:BF₃is a Lewis acid adduct. E) (C₂H₅)₂O and BF₃ are both Lewis acid-base adducts and (C₂H₅)₂O:BF₃is a Lewis acid.

Question

(C₂H₅)₂O is a Lewis base because it donates an electron pair, BF₃ is a Lewis acid because it accepts an electron pair, and (C₂H₅)₂O:BF₃ is the resulting Lewis acid-base adduct.
