Questions & Step-by-Step Solutions
Which of the following is the correct IUPAC name for the compound CH3-CH2-CH(CH3)-COOH?
Step 1: Identify the longest continuous chain of carbon atoms in the compound CH3-CH2-CH(CH3)-COOH.
Step 2: Count the number of carbon atoms in the longest chain. There are 4 carbon atoms.
Step 3: Determine the functional group present. The -COOH group indicates that this is a carboxylic acid.
Step 4: Number the carbon atoms in the longest chain starting from the end closest to the -COOH group. This gives us the following numbering: 1 (COOH), 2, 3, 4.
Step 5: Identify any substituents on the carbon chain. There is a methyl group (CH3) attached to the second carbon.
Step 6: Combine the information to write the IUPAC name. The longest chain is butanoic acid (4 carbons), and there is a methyl group on the second carbon, making it 2-Methylbutanoic acid.
