Identify the base(s) that can deprotonate CH3COOH (pKa=4.756). The conjugate acid products produced from the deprotonation of CH3COOH and their pka values are given in parentheses. Check all that apply.
### Evaluation of Acids and Their Conjugate Bases When determining the strength of an acid, the \( pK_a \) value is a critical factor. Below is a list of various acid-base pairs with their respective \( pK_a \) values: 1. **ICH\(_2\)COO\(^-\)** - Parent Acid: ICH\(_2\)COOH - \( pK_a = 3.2 \) 2. **CH\(_2\)NO\(_2^-\)** - Parent Acid: CH\(_3\)NO\(_2\) - \( pK_a = 10.2 \) 3. **CCl\(_3^-\)** - Parent Acid: CHCl\(_3\) - \( pK_a = 25 \) 4. **Br\(^-\)** - Parent Acid: HBr - \( pK_a = -9 \) 5. **NH\(_3\)** - Parent Acid: NH\(_4^+\) - \( pK_a = 9.4 \) ### Option: - None of the above ### Explanation: - **\( pK_a \) Values:** - Lower \( pK_a \) values indicate stronger acids. - Negative \( pK_a \) values are characteristic of very strong acids. - **Evaluation Notes:** - ICH\(_2\)COOH is a relatively strong acid with a low \( pK_a \). - CH\(_3\)NO\(_2\) and NH\(_4^+\) are weak acids. - CHCl\(_3\) has a very high \( pK_a \), indicating it is a very weak acid. - HBr is an extremely strong acid with a negative \( pK_a \). This assessment aids in understanding the relative strengths of these acids and their conjugate bases within a chemical context.
