**Instructions:** Refer to the previous question, and rank the conjugate bases of acids in the order of increasing base strength (1 as least and 4 as most basic). - **A⁻** [Dropdown menu for ranking] - **B⁻** [Dropdown menu for ranking] - **C⁻** [Dropdown menu for ranking] - **D⁻** [Dropdown menu for ranking] In this exercise, you are required to assess the basicity of the conjugate bases, ranging from least basic (rank 1) to most basic (rank 4). Use the dropdown menus to select the appropriate rank for each conjugate base.

**Acid Strength Ranking Problem** Given the \( K_a \) values for the following acids, rank these acids in the order of increasing acid strength (1 as least acidic and 4 as most acidic). - **HA:** \( K_a = 5.8 \times 10^{-4} \) - **HB:** \( K_a = 4.1 \times 10^{-4} \) - **HC:** \( K_a = 3.9 \times 10^{-3} \) - **HD:** \( K_a = 6.2 \times 10^{-5} \) *Note:* Previous attempt results are marked with checkboxes and lines, indicating prior selections. ### Explanation: The \( K_a \) value represents the acid dissociation constant, a measure of the strength of an acid in solution. The higher the \( K_a \), the stronger the acid. In this set, the acids should be ranked by their \( K_a \) values in descending order to reflect increasing acidity. ### Ranking: 1. **HD** (Least acidic) 2. **HB** 3. **HA** 4. **HC** (Most acidic) The ranking was based on increasing \( K_a \) values: - HD has the smallest \( K_a \), indicating weakest acidity. - HC has the largest \( K_a \), indicating strongest acidity.

Expert Solution
Step 1

Given Ka values of HA, HB, HC and HD are

HA Ka = 5.8 * 10-4

HB Ka = 4.1 * 10-4

HC Ka = 3.9 * 10-3

HD Ka = 6.2 * 10-5
