AI Generated Solution

To determine the number of carboxylic acids that are more acidic than acetic acid (CH₃COOH) among the given options, we need to analyze the effect of substituents on the acidity of each compound. The acidity of carboxylic acids is influenced by the stability of the carboxylate ion formed after deprotonation. Electron-withdrawing groups (EWGs) increase acidity by stabilizing the negative charge on the carboxylate ion, while electron-donating groups (EDGs) decrease acidity. ### Step-by-Step Solution: 1. **Identify Acetic Acid as the Reference:** - Acetic acid (CH₃COOH) will be our reference point for acidity. 2. **Analyze Each Compound:** ...
