Text Solution

AI Generated Solution

To explain why the pKa value of 4-nitrobenzoic acid is lower than that of benzoic acid, we can break down the explanation into several steps: ### Step 1: Understanding pKa and Ka - **Definition**: pKa is the negative logarithm of the acid dissociation constant (Ka). - **Relation**: A lower pKa value indicates a stronger acid, as it corresponds to a higher Ka value. ### Step 2: Comparing Benzoic Acid and 4-Nitrobenzoic Acid - **Benzoic Acid (C6H5COOH)**: This is a simple carboxylic acid without any substituents that affect its acidity significantly. ...
