Which of the following statements about a Brønsted-Lowry base is true?
A)The net charge may be zero,positive,or negative.
B)All Brønsted-Lowry bases contain a lone pair of electrons or a π bond.
C)All Brønsted-Lowry bases contain a proton.
D)The net charge may be zero or positive.

Question

Quizplus · Accepted Answer

According to the Brønsted-Lowry definition, a base is a species that can accept a proton (H+). Bases that contain a lone pair of electrons or a π bond are capable of accepting a proton, which makes them Brønsted-Lowry bases. Therefore, statement B is true. Statements A, C, and D are false because a Brønsted-Lowry base does not necessarily contain a net charge or a proton.
