Answer:
of the following statements about a Brønsted-Lowry base is true? Group of answer choices
i. All Brønsted-Lowry bases contain a lone pair of electrons or a π bond.
ii. The net charge may be zero, positive, or negative.
iii. The net charge may be zero or positive.
iv. All Brønsted-Lowry bases contain a proton.
Answer: Only i. Is true.
Bronsted Lowry defines acid as proton donors. Bronsted Lowry defines the base species as that which can accept proton.
Explanation:
In order to accept a proton, a Brønsted-Lowry base must have at least one lone pair of electrons or pi (π) bond to form a new bond with a proton.
An acid-base reaction using the Brønsted-Lowry definition, is any reaction in which a proton is transferred from an acid to a base. We can use the Brønsted-Lowry definitions to discuss acid-base reactions in any solvent, as well as those that occur in the gas phase
