Q: Which of the following is the correct IUPAC name for C6H5-CH2-CH2-COOH?
Solution: The compound has a phenyl group attached to a butanoic acid structure, making it Phenylbutanoic acid.
Steps: 4
Step 1: Identify the main functional group in the compound. Here, the compound has a carboxylic acid group (-COOH).
Step 2: Count the number of carbon atoms in the longest chain that includes the carboxylic acid. The chain has 4 carbon atoms (butanoic acid).
Step 3: Identify the substituent attached to the main chain. There is a phenyl group (C6H5) attached to the second carbon of the butanoic acid chain.
Step 4: Combine the names of the substituent and the main chain. The phenyl group is attached to butanoic acid, so the name becomes Phenylbutanoic acid.
