Which of the following is not Bronsted-Lowery base?
Correct answer: C. BF₃
- A. H₂O
- B. HCO₃⁻
- C. BF₃
- D. ROH
Explanation
The correct answer is BF₃ because a Bronsted-Lowry base is defined as a substance that can accept a proton (H⁺). BF₃ does not accept protons; instead, it acts as a Lewis acid by accepting electron pairs. Conversely, H₂O, HCO₃⁻, and ROH can all accept a proton, fitting the definition of Bronsted-Lowry bases.
