The correct Answer is:
To determine the structure and classification of 3-pentanol, we can follow these steps: ### Step 1: Identify the Structure of 3-Pentanol 3-Pentanol is an alcohol with a five-carbon chain (pentane) and an -OH (hydroxyl) group attached to the third carbon. The structure can be represented as follows: ``` CH3-CH2-CHOH-CH2-CH3 ``` ### Step 2: Count the Carbon Atoms In the structure of 3-pentanol, we have a total of five carbon atoms. The carbon chain is numbered from one end to the other, ensuring that the hydroxyl group is attached to the third carbon. ### Step 3: Determine the Degree of Alcohol To classify the alcohol, we need to look at the carbon atom that is directly bonded to the hydroxyl (-OH) group. In 3-pentanol, the -OH group is attached to the third carbon. - The third carbon is connected to: - One carbon atom on one side (the second carbon) - One carbon atom on the other side (the fourth carbon) Since the carbon connected to the -OH group is attached to two other carbon atoms, it is classified as a secondary alcohol. ### Step 4: Conclusion Based on the analysis, we conclude that 3-pentanol is a secondary alcohol. ### Final Answer 3-Pentanol is a secondary alcohol. ---
