Q: What is the IUPAC name for the compound C6H5-CH(CH3)-OH?

Solution: The compound has a phenyl group and a hydroxyl group on the second carbon of a three-carbon chain, hence it is Phenylpropan-2-ol.

Steps: 6

Step 1: Identify the main chain of the compound. The formula C6H5-CH(CH3)-OH indicates a three-carbon chain with a hydroxyl (OH) group.
Step 2: Determine the longest carbon chain. The longest chain here is three carbons long (C-CH-CH3).
Step 3: Number the carbon chain. Start numbering from the end closest to the hydroxyl group. This gives us 1 for the carbon with OH, 2 for the next carbon, and 3 for the last carbon.
Step 4: Identify the substituents. The compound has a phenyl group (C6H5) attached to the second carbon of the chain.
Step 5: Combine the names. The main chain is a propanol (3 carbons with an OH), and since the OH is on the second carbon, it is called propan-2-ol. The phenyl group is attached to the second carbon, so we name it phenylpropan-2-ol.
Step 6: Write the final IUPAC name. The complete IUPAC name for the compound is Phenylpropan-2-ol.
