Questions & Step-by-Step Solutions
Which of the following is the correct IUPAC name for the compound with the formula C6H5-CH2-CH2-COOH?
Step 1: Identify the main functional group in the compound. The formula C6H5-CH2-CH2-COOH indicates that there is a carboxylic acid group (-COOH).
Step 2: Count the number of carbon atoms in the longest chain that includes the carboxylic acid. The chain is CH2-CH2-COOH, which has 3 carbon atoms.
Step 3: Recognize that the longest carbon chain with the carboxylic acid is a butanoic acid because it has 4 carbon atoms (including the one in the -COOH group).
Step 4: Identify the phenyl group (C6H5) attached to the butanoic acid. The phenyl group is a benzene ring that is connected to the butanoic acid.
Step 5: Combine the names of the phenyl group and the butanoic acid. The correct IUPAC name is Phenylbutanoic acid.
