To determine the order of decreasing boiling points for the given alcohols: Pentan-1-ol, 2-Methylbutan-2-ol, and 3-Methylbutan-2-ol, we need to analyze the structure and branching of each compound. ### Step 1: Identify the Structures 1. **Pentan-1-ol**: This is a straight-chain alcohol with the structure CH3-CH2-CH2-CH2-OH. It has 5 carbon atoms and is a primary alcohol. 2. **2-Methylbutan-2-ol**: This compound has a branched structure with the structure CH3-CH(OH)-CH(CH3)-CH3. It has 5 carbon atoms and is a tertiary alcohol. 3. **3-Methylbutan-2-ol**: This compound also has a branched structure with the structure CH3-CH(CH3)-CH(OH)-CH3. It has 5 carbon atoms and is a secondary alcohol. ### Step 2: Determine the Type of Alcohol ...
