Step 1: Identify the species labeled as 'Conjugate Acid' in the image. The molecule with the carbonyl group (C=O) and a hydrogen attached to the alpha carbon is labeled as the conjugate acid.

Step 2: Analyze the reactants. The molecule with the negatively charged nitrogen (NH⁻) is a base because it can accept a proton.

Step 3: Examine the products. The molecule with the negatively charged oxygen (O⁻) is the conjugate base, as it results from the conjugate acid losing a proton.

Step 4: Identify the second product. The molecule with the neutral amine group (H₂N) is the conjugate acid of the base, as it results from the base gaining a proton.

Step 5: Summarize the labels: The reactants are 'Conjugate Acid' and 'Base,' while the products are 'Conjugate Base' and 'Conjugate Acid.' This follows the Bronsted-Lowry acid-base theory.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Acids and Bases

In organic chemistry, acids are substances that can donate a proton (H+) to another substance, while bases are substances that can accept a proton. This concept is fundamental to understanding acid-base reactions, where the transfer of protons leads to the formation of conjugate acids and bases.

Conjugate Acid and Conjugate Base

A conjugate acid is formed when a base accepts a proton, while a conjugate base is formed when an acid donates a proton. This relationship is crucial in acid-base chemistry, as it helps to identify the species involved in a reaction and predict the direction of equilibrium.

Equilibrium in Acid-Base Reactions

Acid-base reactions often reach a state of equilibrium, where the rates of the forward and reverse reactions are equal. Understanding this concept allows chemists to predict the favored direction of a reaction based on the strengths of the acids and bases involved, which is essential for labeling the species correctly in the given reaction.
