When a primary alcohol undergoes controlled, partial oxidation, it loses two hydrogen atoms (one from the oxygen and one from the carbon it's attached to) to form a carbonyl group (C=O) at the end of the carbon chain. This functional group is characteristic of an aldehyde. Step 1: Understand the reactant. A primary alcohol has the general formula R-CH_2-OH . The hydroxyl group (-OH) is attached to a carbon atom that is bonded to only one other carbon atom. Step 2: Understand the reaction. Controlled, partial oxidation means that the reaction is stopped after the first oxidation step, preventing further oxidation to a carboxylic acid. Common reagents for this include pyridinium chlorochromate (PCC). Step 3: Determine the product. Oxidation of a primary alcohol removes hydrogen atoms, forming a carbonyl group. R-CH_2-OH controlled oxidation R-CHO The product, R-CHO, is an aldehyde. Step 4: Compare with the given options. A. Ester: Formed from a carboxylic acid and an alcohol. B. Ketone: Formed from the oxidation of a secondary* alcohol. C. Aldehyde: Formed from the controlled oxidation of a primary* alcohol. D. Ether: Formed by dehydration of alcohols or Williamson ether synthesis. The correct answer is C. The final answer is C. Aldehyde. Send me the next one 📸
