**Instructions:** Draw the product of the reaction shown below. Use wedge and dash bonds to indicate stereochemistry where appropriate. Ignore inorganic byproducts. **Reaction Details:** The starting compound is a branched alcohol. It features a hydroxyl group (OH) attached to a carbon chain that has both an upward and a horizontal branching. **Reagent Involved:** - **KMnO₄:** Potassium permanganate is the reagent used in this oxidation reaction. **Product Drawing:** Make use of the "Select to Draw" area to sketch the structure of the product, ensuring to highlight stereochemistry using wedge and dash bonds if needed.

**Ranking Carboxylic Acids by pKa** **Objective:** Rank the given carboxylic acids from lowest to highest pKa. Remember, a lower pKa indicates a more acidic compound. **Compounds to Rank:** 1. **Compound 1:** Contains a bromine (Br) atom attached to the second carbon from the carboxyl group. 2. **Compound 2:** Features a bromine (Br) atom at the third carbon from the carboxyl group. 3. **Compound 3:** Has a bromine (Br) atom on the fourth carbon from the carboxyl group. 4. **Compound 4:** Contains a bromine (Br) on the third carbon, but a different chain structure from Compound 2. **Ranking Options:** A) 1 < 2 < 3 < 4 B) 4 < 3 < 2 < 1 C) 4 < 1 < 3 < 2 D) 1 < 3 < 2 < 4 E) 2 < 3 < 4 < 1 **Explanation:** - The acidity of carboxylic acids is influenced by the presence of electronegative substituents like bromine (Br). - Bromine is an electron-withdrawing group that stabilizes the carboxylate ion, making the acid more acidic. - The closer the bromine is to the carboxyl group, the more acidic the compound due to a greater inductive effect. **Conclusion:** Analyze the position of the bromine in each compound relative to the carboxyl group to determine the correct ranking from lowest to highest pKa.
