The correct Answer is:
To determine the structure of the alcohol that, upon oxidation, yields both acetic acid (CH₃COOH) and 2-pentanol (CH₃CH(OH)CH₂CH₂CH₃), we can follow these steps: ### Step-by-Step Solution: 1. **Identify the Products**: The products of the oxidation are acetic acid (CH₃COOH) and 2-pentanol (CH₃CH(OH)CH₂CH₂CH₃). This indicates that the starting alcohol must be a secondary alcohol since it can produce two different products upon oxidation. 2. **Determine the Structure of Acetic Acid**: Acetic acid has the structure CH₃COOH. This suggests that one of the oxidation products is derived from a carbon chain that includes a carbonyl group (C=O) at the end. 3. **Determine the Structure of 2-Pentanol**: The structure of 2-pentanol is CH₃CH(OH)CH₂CH₂CH₃. This indicates that the alcohol has a hydroxyl (-OH) group on the second carbon of a five-carbon chain. 4. **Combine the Information**: Since the oxidation of the alcohol yields both acetic acid and 2-pentanol, we can infer that the alcohol must be a secondary alcohol with a five-carbon chain. The presence of both products suggests that the alcohol must be capable of being oxidized to form both a carboxylic acid and an aldehyde. 5. **Propose the Structure of the Alcohol**: The alcohol that fits this description is 3-pentanol (CH₃CH₂CH(OH)CH₂CH₃). Upon oxidation: - 3-pentanol can be oxidized to form 2-pentanoic acid (which can further oxidize to acetic acid) and 2-pentanol. 6. **Final Structure**: Therefore, the structure of the alcohol is: \[ \text{CH}_3\text{CH}_2\text{CH(OH)}\text{CH}_2\text{CH}_3 \] This is 3-pentanol.
