Q
Q: Which of the following is the correct IUPAC name for the compound CH3-CH2-CH(CH3)-OH?
Solution: The compound has a hydroxyl group on the second carbon of a four-carbon chain, making it 2-Butanol.
Steps: 5
Step 1: Identify the longest carbon chain in the compound. The longest chain here has four carbon atoms (CH3-CH2-CH(CH3)-OH).
Step 2: Number the carbon chain starting from the end closest to the hydroxyl group (OH). This gives us the following numbering: 1-2-3-4.
Step 3: Determine the position of the hydroxyl group (OH). It is on the second carbon (C2).
Step 4: Identify the type of alcohol based on the carbon chain. Since there are four carbons and the hydroxyl group is on the second carbon, the compound is a butanol.
Step 5: Combine the position of the hydroxyl group with the name of the alcohol. This gives us the name 2-Butanol.
