1. Which of the following is not a Bronsted–Lowry base?

  • A.
  • B. F-
  • C.
  • D. H — O — N = O

Correct Answer: D

A Bronsted-Lowry base is defined as a proton acceptor. Ammonia, fluoride, and water—choices (A), (B), and (C), respectively—each accept a proton. Choice (D), HNO2, is a far better Bronsted-Lowry acid, donating a proton to solution.
