Question
**Question 5:** Identify the Brønsted-Lowry base (not the conjugate base) in the equilibrium depicted below. **Chemical Reaction Diagram:** The reaction is shown with the following components: - Reactants: - Compound (a): Acetone (C₃H₆O), depicted as a structure with a C=O bond and two CH₃ groups attached to the carbon. - Compound (b): Ethanol (CH₃CH₂OH). - Compound (c): Sulfuric acid (H₂SO₄). - Products: - Compound (d): Protonated acetone (C₃H₇O⁺), where a hydrogen ion (H⁺) is added to the oxygen of the carbonyl group in acetone. - Compound (e): Ethanol (CH₃CH₂OH), unchanged from the reactant side. - Compound (f): Hydrogen sulfate ion (HSO₄⁻), remaining from the dissociation of sulfuric acid. The reaction is shown as reversible, indicated by a double-headed arrow. **Explanation:** In the context of Brønsted-Lowry acid-base theory, a base is a substance that can accept a proton (H⁺). In this equilibrium, the Brønsted-Lowry base is ethanol (b/e: CH₃CH₂OH), as it does not accept a proton in this particular interaction, and the focus should be on identifying bases prior to any reaction that results in a conjugate acid/base pair.
