Q
Q: What is the IUPAC name for the compound with the structure CH3-CH(CH3)-C(=O)-OH?
Solution: The compound is a carboxylic acid with a four-carbon chain and a methyl group on the second carbon, hence 2-methylbutanoic acid.
Steps: 5
Step 1: Identify the longest carbon chain in the structure. The longest chain has four carbon atoms (butane).
Step 2: Determine the functional group. The structure has a carboxylic acid group (-COOH) at the end of the chain.
Step 3: Number the carbon chain starting from the end closest to the carboxylic acid group. This gives us the following numbering: 1 (carboxylic acid), 2, 3, 4.
Step 4: Identify any substituents on the carbon chain. There is a methyl group (CH3) on the second carbon.
Step 5: Combine the information. The longest chain is butane, and there is a methyl group on the second carbon, making it 2-methylbutanoic acid.
